Aviatrix Controller 8.2.0 Release Notes

Release Date: 22 December 2025 Release Notes Last Updated: 5 October 2026

​

Corrected Issues in Aviatrix Release 8.2.0

Issue	Description
AVX-64447	Fixed an issue where toggling between Active/Active HA and Active/Standby modes for Site2Cloud connections was not working properly. Users can now successfully switch between these high availability modes as expected.
AVX-66324	Fixed an issue where bell notifications were missing for Distributed Cloud Firewall (DCF) L7 rules between Kubernetes pods and VMs when using HA gateways. Previously, traffic would work intermittently when DCF L7 rules were applied between Kubernetes services and VMs in different VPCs with HA gateways. The system now properly generates notifications when these rules are applied.
AVX-67530	Fixed an issue where the traffic count displayed in the Controller interface could be inaccurate when using Distributed Cloud Firewall (DCF) with external groups that include multiple IP ranges. The Controller now reports traffic statistics correctly for DCF rules involving external groups, providing accurate visibility for monitoring, analysis, and validation of firewall policy behavior.
AVX-68013	Resolved an issue where Spoke-to-Transit attachments initiated through Terraform could fail with a decode check_task_status failed error. The Controller now returns a valid response consistently, preventing Terraform failures during Spoke-to-Transit attachment operations.
AVX-68108	Fixed an issue where upgrading the Controller from version 8.0.30 to 8.1.10 would display a “Service temporarily unavailable” error message. The system now properly handles the service restart during the upgrade process.
AVX-68606	Resolved an issue where Edge gateway upgrades from version 8.1 to 8.1.10 could cause temporary traffic disruption due to service restarts during the upgrade process. The upgrade workflow now handles service restarts more effectively, reducing traffic impact during Edge gateway upgrades, including in large-scale deployments.
AVX-68726	Resolved an issue on Azure Controllers where Controller Security Group Management could cause gateway deployments to fail. The issue occurred when security group rules were not updated correctly while creating multiple gateways or HA gateways, which led to duplicate rule errors and prevented additional gateways from being deployed. Security group rules are now applied correctly, and gateway deployments succeed as expected.
AVX-69733	Resolved an issue where the ESTABLISHED rule disappeared after a Public Subnet Filtering (PSF) gateway image upgrade. This issue affected PSF gateways using the legacy stateful firewall on Controller versions 7.1 and later, and could result in traffic disruption after the upgrade. The rule is now preserved during PSF gateway image upgrades.
AVX-70123	Fixed an issue with database schema type definitions that could trigger migration errors during the Controller upgrade process. The schema now uses the correct database type definition, ensuring compatibility with migration logic and preventing upgrade failures.
AVX-70253	Fixed an issue where FireNet deployments with bootstrap enabled could fail in Google Cloud due to changes in how GCP credentials were handled during the bootstrap process. The bootstrap workflow has been updated to correctly retrieve and use GCP credentials, ensuring FireNet deployments with bootstrap complete successfully in Google Cloud environments.
AVX-70506	Fixed an issue where deploying multiple GCP gateways through Terraform resulted in ResourceDuplicateId errors. Users can now successfully deploy multiple gateways in GCP regions without encountering resource ID conflicts.
AVX-70543	Fixed an issue where when DPI/IDS or Layer7 policies are configured with “Destination: Anywhere” on HA-enabled spoke gateways where the destination smart group contains private CIDRs, the policies become invalid and cause traffic drops.
AVX-70864	Fixed an issue where in Controller version 8.2.0, gateways may remain in a Configuration Not Up-to-Date state when applying Distributed Cloud Firewall (DCF) policies under certain conditions.
AVX-70958	Fixed an issue where when clients use HTTP/2 connections, TrafficServer incorrectly reuses origin connections, potentially causing connection handling issues in MITM SNI verification scenarios.
AVX-71087	Fixed an issue where the default access control rules did not properly allow ICMP traffic used for debugging. The updated rules ensure ICMP-based troubleshooting continues to work after upgrades.
AVX-71217	Resolved an issue where the VRRP state file could become empty when upgrading AEP and self-managed Edge-as-Spoke gateways in active-active HA configurations from version 7.2 to 8.0.30. With this fix, VRRP primary and backup state information is preserved during the upgrade, and newly created Edge-as-Spoke gateways with VRRP configuration no longer remain in the Initializing state.
AVX-71719	Fixed an issue where ICMP traffic passing through Suricata inspection on gateways only triggered alert rules once until the Suricata process restarted. Alert rules now fire consistently for all matching traffic.
AVX-71720	Fixed an issue where decrypted POST traffic passing through the ATS tee plugin could cause PSF gateway crashes during request body processing. The tee plugin now correctly handles POST request bodies without crashing.
AVX-71807	Resolved an issue where eBPF packet marking could fail on transit gateways with Network Segmentation enabled, causing traffic to be associated with incorrect network domains. The packet marking logic has been corrected to ensure Network Segmentation policies are enforced consistently without requiring service restarts.
AVX-72207	Fixed an issue where upgrading OpenVPN gateways to Controller version 8.1 with profiles containing FQDN-based policies resulted in service disruption due to a DNS resolution limitation. Users can now access whitelisted FQDNs in OpenVPN Profiles after upgrading.
AVX-72862	Fixed an issue where the documentation did not clarify that toggling High Performance Encryption (HPE) has the same limitations as primary gateway deletion, including restrictions when Site-to-Cloud, FireNet, or AWS TGW connections are present.
AVX-74711	Fixed an issue where the gateway firewall left an unnecessary TCP port open due to a misconfiguration in the routing service.

​

Known Issues in Aviatrix Release 8.2.0

Issue	Description
AVX-62003	Azure gateway image upgrades may fail when the Controller does not have the required Azure image subscription access. During the upgrade, the system deletes the existing gateway before validating subscription availability, which can result in gateway deletion without a replacement being created. This leaves dangling gateways in the Controller and can cause potential service outages. Impact: Existing gateways may be deleted during image upgrade Replacement gateway creation fails due to missing subscription Customers may experience connectivity loss and dangling gateway entries in the Controller Manual intervention required, leading to support escalations Workaround: None. To avoid outages, ensure the Controller subscription includes access to the required Azure image before attempting upgrades.
AVX-62299	When upgrading from Controller version 7.1 to 7.2 or 8.0, Spoke Gateways with routing through a Public Subnet Filtering (PSF) Gateway may fail to upgrade and become unreachable if the PSF Gateway has not been upgraded first. This issue affects AWS environments where Spoke Gateway route tables are configured to point to a PSF Gateway. Workaround: To avoid this issue, follow the correct upgrade sequence:1. Upgrade the PSF Gateway first. 2. Wait for the PSF Gateway upgrade to complete successfully. 3. Then upgrade the dependent Spoke Gateways.
AVX-62506	During a gateway software upgrade, traffic matching DCF WebGroup rules may be briefly dropped during the upgrade. This impacts both Layer 7 (HTTP/HTTPS) and Layer 4 traffic and occurs across all supported cloud providers (AWS, Azure, and GCP). The disruption typically lasts a few seconds but may vary depending on gateway load and policy complexity. Workaround: None Recommendations: Schedule gateway upgrades during maintenance windows or low-traffic periods. Use HA deployments and upgrade gateways one at a time in HA pairs. * Monitor logs for “Failed to load policy” messages to confirm when policies are reloaded.
AVX-64868	In some scenarios involving rapid VRRP state transitions, the keepalived VRRP state may not be reported accurately to the Controller. This can result in temporary discrepancies between the actual VRRP status and what is displayed in the Controller UI, leading to confusion and difficulties during troubleshooting. Impact: Controller UI may show incorrect VRRP status such as both peers reporting Primary or Initializing No impact on actual VRRP traffic handling or failover behavior. Workaround: Use diagnostic logs to verify actual VRRP state
AVX-65016	In some environments, the Firewall state may not recover from Unaccessible after the first vendor integration failure. This issue has been observed when integrating with third-party firewall vendors, leaving the gateway firewall state stuck even after the environment stabilizes. Impact: Firewall integration appears stuck in Unaccessible state Recovery does not occur automatically after initial failure * May require manual intervention to restore proper firewall state reporting Workaround: Contact Aviatrix Support for manual correction.
AVX-66631	Transit gateways with large-scale tunnel deployments (1300+ tunnels) may experience extended traffic loss during image upgrades. Although the image upgrade completes successfully, traffic may remain down for several minutes afterward due to delayed tunnel reconfiguration. Impact: Traffic loss may persist after image upgrade completes Route service startup is blocked until all tunnels are sequentially reconfigured Configuration push may time out with Context cancelled during Phase 1 Create error Workaround: Schedule maintenance windows to account for potential traffic loss beyond upgrade completion. Consider staggering upgrades across transit gateways to reduce impacts. Monitor tunnel and route service status post-upgrade through the CoPilot UI.
AVX-67126	Dry-run validation may fail when upgrading the Controller from version 8.0.10 to 8.1.0 due to a gateway version mismatch error. This occurs when the upgrade path starts from 8.0.0, progresses to 8.0.10 successfully, but encounters a dry-run failure when proceeding to 8.1.0. Workaround: None.
AVX-67571	In Oracle Cloud Infrastructure (OCI) environments, OpenVPN clients cannot connect to VPN gateways configured with DUO multi-factor authentication (MFA). Connection attempts fail with ECONNREFUSED errors during tunnel establishment, preventing authentication from completing. Impact: VPN tunnels cannot be established to DUO-enabled OCI gateways Only affects OCI deployments with DUO MFA * Other authentication methods (OKTA, LDAP) work normally Workaround: No current workaround. Users may temporarily switch to OKTA or LDAP authentication if feasible.
AVX-68561	In large-scale deployments with 1300+ gateways, enabling Distributed Cloud Firewall Site-to-Cloud (DCF S2C) can cause gateway configurations to become out of sync with the Controller. Even after disabling DCF S2C, the issue may persist and lead to elevated Controller resource usage. Impact: Gateway configurations may show as out of sync in the Controller UI Controller CPU load (conduit process) increases significantly Performance degradation may occur during DCF S2C operations Issue may persist after disabling DCF S2C Workaround: Monitor Controller CPU usage before enabling DCF S2C in large-scale environments. Consider enabling DCF S2C during scheduled maintenance windows. * For deployments with 1300+ gateways, evaluate the necessity of DCF S2C functionality.
AVX-68887	When attaching VPN users to profiles using the attach_vpn_user_to_profile API, the CoPilot or Controller UI may continue to display the user profile as N/A even though the attachment operation completes successfully. In some cases, users later reappear as active but still show no profile association in the UI. This results in a display inconsistency between the UI and the backend state. Impact: VPN user profile assignments may appear unsuccessful in the UI, which can cause confusion during profile management. There is no functional impact: the VPN profile is correctly assigned in the backend, and users can connect to the VPN as expected. Affected Scenario: OpenVPN profile management operations that use API-based user-to-profile attachment. Workaround: None.
AVX-69342	When a Controller experiences out-of-memory conditions followed by upsizing and restart, duplicate resource ID entries may be created in the database. This prevents the Controller from starting properly and blocks access to the web UI. Impact: Controller fails to start after restart Web UI becomes inaccessible * Database contains duplicate resource entries for GCE networks and other resources Affected Scenario: Controllers that have experienced memory issues, been upsized, and restarted may encounter this database corruption. Workaround: Connect directly to the Controller database and manually remove the duplicate resource ID entries to restore normal operation.
AVX-71122	In some environments, after the Identity Provider (IdP) rotates its SAML signing certificate, the Aviatrix Controller may fail to fetch and update the new certificate from the configured metadata URL. As a result, the Controller continues to use a stale certificate, which causes signature verification errors during SAML authentication. Impact: SAML single sign-on (SSO) authentication fails. Users may experience repeated login failures or timeouts and are unable to access the Controller dashboard using SAML. Workaround: Contact Aviatrix Support to manually update the SAML certificate on the Controller.
AVX-71135	The AM4.0 database migration may fail when the tunnel database timestamp field contains string values instead of the expected integer type. This can block Controller upgrades that include the AM4.0 migration step. Impact: Controller upgrade may fail during database migration The Controller will remain on the previous version Workaround: Contact Aviatrix Support for assistance with correcting the database field values before retrying the upgrade.
AVX-71245	Additional Distributed Cloud Firewall (DCF) log support records end-session events for IDS and IPS signature matches. These logs include a reason field indicating the match type (IPS_POLICY_DENY or IDS_POLICY_ALERT) along with the Signature ID (SID) of the matched rule. Due to a bug, the end-session log is omitted when Decryption is not enabled for Intrusion Analysis. Impact: Missing end-session log entries for IDS/IPS signature matches when Decryption is disabled No impact to DCF policy actions * No impact to existing Intrusion Analysis logs Affected Version: 8.2.0 Workaround: Enable Decryption under Intrusion Analysis to ensure end-session logs are generated.
AVX-71320	Source IP translation may not work correctly for policy-based Site-to-Cloud connections with SNAT configuration when traffic is sent from cloud to site. Impact: Cloud-to-site traffic through policy-based S2C tunnels may use incorrect source IP Remote site firewalls or routing policies may drop or misroute the traffic Workaround: No workaround is available for this issue. Upgrade to Controller 10.1.0 or later, where this issue is fixed.
AVX-71441	When upgrading gateways from version 8.1.20 to 8.2.0, in rare cases the gateway can enter an infinite retry loop attempting to download a non-existent configuration file from the Controller, causing the upgrade process to fail completely. Impact: Gateway upgrade fails and cannot be completed. Gateway becomes stuck in upgrade state. * Network connectivity through the affected gateway will be disrupted. Workaround: Retry the gateway upgrade operation from the Controller UI or Copilot UI. If the issue persists, perform an image upgrade of the impacted gateway.
AVX-71630	On Azure Aviatrix gateways with accelerated networking enabled and using Distributed Cloud Firewall (DCF) features, intermittent traffic drops may occur after upgrading from a version earlier than 7.2.2994 to 7.2.2994 or later. This issue is caused by incorrect eBPF filters being applied to the slave eth1 interface during the upgrade process. Affected Scenario: Azure gateways with accelerated networking enabled DCF features enabled Upgrading from a version prior to 7.2.2994 to 7.2.2994 or later Impact: Intermittent traffic drops across affected gateways Workaround: Contact Aviatrix Support for assistance.
AVX-71672	When upgrading the Controller to version 8.1, the database migration may fail if the tunnel rtt_avg field contains None values. The migration logic expects either a numeric value or the string "N/A", and encountering a None value causes the upgrade to stop. Impact: Upgrade to 8.1 cannot complete Controller remains on the previous version Workaround: Contact Aviatrix Support for assistance in correcting the database values before retrying the upgrade.
AVX-71787	When managing Distributed Cloud Firewall (DCF) rules through Terraform with Multi-Writer Policy (MWP), Terraform operations on rulesets containing large number of rules may take significantly longer compared to using the legacy V1 policy list. In environments with large rule sets, each containing 3,000+ DCF rules, the Terraform apply and refresh operations can be up to 20× slower when compared to storing them in the default V1 policy list. This behavior has been observed in environments with hundreds of spokes and high rule volume. This is a direct result of using Terraform sets to track rules more reliably and have more predictable, readable, Terraform diffs. The algorithm used by Terraform is not optimal for very large rulesets. Impact: Terraform apply and refresh operations may take several minutes Large rule sets in DCF environments see increased management latency Automation pipelines may experience delays Affected Scenario: Terraform workflows that create or manage large DCF rulesets under Multi-Writer Policy (MWP). Workaround: Rule sets can be broken up in multiple smaller rule sets under a rule block, this helps manageability. The recommended maximum size for a ruleset is 500-750 rules. Contact Aviatrix Support for further assistance with large-scale DCF Terraform deployments.
AVX-71820	When deploying a load balancer–enabled VPN gateway with an overlapping VPN CIDR on Controller versions 8.0, 8.1, or 8.2, the gateway creation fails. Impact: VPN gateway deployment fails Error message does not clearly indicate the root cause Affected Scenario: Load balancer–enabled VPN gateway deployments on Controller versions 8.0, 8.1, and 8.2. Workaround: Ensure that the VPN CIDR does not overlap with existing gateways behind the load balancer before deployment. Contact Aviatrix Support for assistance.
AVX-71826	In Aviatrix software versions 8.1.x and 8.2.0, the VRRP state file may be empty on AEP and self-managed Edge-as-Spoke gateways configured in active-active HA pairs. This prevents VRRP state updates from being sent from the edge gateways to the Aviatrix Controller, and Aviatrix CoPilot will not display the updated VRRP states. This is a cosmetic issue and there will be no disruption to traffic. Impact: VRRP state information for edge gateways is not shown accurately in Aviatrix CoPilot Aviatrix CoPilot may display both primary and HA edge gateways with the same VRRP state The VRRP state information will not be updated in Aviatrix CoPilot when VRRP failovers occur on the data plane. This is a display-only issue and the data plane will not be disrupted The VRRP state information may show Initializing in Aviatrix CoPilot for Edge-as-Spoke gateways which are created in version 8.1 and 8.2 Affected Scenario: AEP and self-managed Edge-as-Spoke gateways in active-active HA deployments with VRRP enabled upgrade from 8.0 to 8.1 or created in 8.1 and 8.2 Workaround: Contact Aviatrix Support for assistance to help you fix the incorrect display of VRRP states in Aviatrix CoPilot.
AVX-72363	The Controller may display an incorrect warning message during a platform upgrade, stating the release is under development or unsupported. Workaround: Contact Aviatrix Support for assistance.
AVX-72369	When multiple syslog profiles are configured on the Controller, performing a gateway image upgrade results in gateways being removed from syslog profiles that have only a subset of gateways specified in the include list. Impact: Remote syslog logs are no longer forwarded to the configured syslog servers for the affected gateways Workaround: Manually re-add the required gateways to the affected syslog profiles after the upgrade.
AVX-72388	The email notification for internal CA certificate rotation displays with a red error color instead of a yellow warning color, which may cause unnecessary alarm. Workaround: Contact Aviatrix Support for assistance.
AVX-72835	When upgrading to Controller 8.1, the database migration may fail if a High Availability Gateway (HAGW) entry appeared before its corresponding primary gateway in the database collection. During migration, the process relies on a strict ordering: primary gateway data must be initialized before the HAGW is processed to correctly populate gateway group data. The migration may fail or leave behind gateway entries in the wrong order in the database, which can lead to further issues. Impact: The upgrade to Controller 8.1 may fail to complete Gateway entries may be stored in an incorrect order in the database Workaround: Contact Aviatrix Support for assistance.
AVX-72871	Controller software upgrade to version 8.1 may fail with an error indicating that the page must be reloaded to complete the upgrade, due to an issue with the database migration when the database contains string values instead of integers for the cloud_type field. Impact: The upgrade to version 8.1 will not be completed The Controller will remain on the previous version Workaround: Contact Aviatrix Support for assistance in correcting the database values before retrying the upgrade.
AVX-72881	During upgrades from older Aviatrix Controller versions to versions 8.1.20 and 8.2.0, NetflowMode migration may fail due to incomplete NetflowMode records stored in databases. This issue arises because older Controller versions allowed NetflowMode records with missing or empty fields, such as an empty port value. In newer releases, the migration enforces stricter validation and fails when encountering these incomplete records, causing the migration to fail. Impact: NetflowMode migration may fail during controller upgrade Upgrade process may be blocked until the invalid records are addressed Affected Scenario: Controllers upgraded from older versions with legacy MongoDB NetflowMode records Environments where NetFlow logging services were disabled but still contain incomplete configuration entries Workaround: If assistance is needed, contact Aviatrix Support.
AVX-72932	The CloudWatch agent migration may fail when processing legacy database records that are missing required fields, preventing the migration from completing successfully. Workaround: Contact Aviatrix Support for assistance.
AVX-72940	Creating a new gateway with the same name as an existing gateway may cause local files of the existing gateway to be deleted when the creation fails. The existing gateway name disappears from the Controller CLI when this issue occurs. Impact: SSH access to the existing gateway may stop working Gateway recovery may require manual intervention Workaround: Do not reuse gateway names. Contact Aviatrix Support if recovery is required.
AVX-72966	Launching an AWS gateway may fail the public subnet validation check due to a delay in subnet route table association updates from the cloud provider. Workaround: Contact Aviatrix Support for assistance.
AVX-73061	The Cloud Asset Inventory (CAI) service has a memory leak in its L1 cache. When cloud instances such as VMs are removed from the cloud provider, the associated network interfaces remain cached and are never cleaned up. Impact: In environments that regularly cycle VMs (such as those using spot instances), the CAI service memory consumption grows over time and is never reclaimed. This can lead to high memory usage by the CAI service, potentially affecting Controller performance. Workaround: Contact Aviatrix Support for assistance with periodic CAI service restarts to reclaim memory.
AVX-73182	An invalid VPC ID format during spoke gateway initialization can cause a failed lookup and may result in a duplicate VPC object being created. Workaround: Contact Aviatrix Support for assistance.
AVX-73377	During gateway software upgrade on FQDN-enabled gateways, the FQDN traffic-filtering processes may be killed and restarted, resulting in a traffic outage of approximately 10 minutes after the upgrade completes. Impact: Traffic through FQDN-enabled gateways is interrupted for approximately 10 minutes during gateway software upgrade Affects gateways with FQDN filtering enabled Workaround: Schedule gateway software upgrades during maintenance windows to minimize the impact of the temporary traffic outage.
AVX-73436	When using the update_spoke_vpc_route_table API to onboard an Azure route table, the default route (0.0.0.0/0) is not programmed in the spoke VNET route table if the Spoke Gateway has learned the default route from any of the following sources: An attached Egress Transit Gateway (Transit with egress functionality enabled) A Transit Gateway that learned the default route via an external Site-to-Cloud (S2C) connection (for example, from an on-premises network or third-party appliance advertising 0.0.0.0/0 over IPSec/BGP) Another Spoke Gateway that is propagating the default route within the Aviatrix network In all of the above cases, although the Spoke Gateway has successfully learned and installed the default route in its own routing table, the route is not re-programmed into the associated Azure VNET route table during the onboarding operation. Impact: Default route (0.0.0.0/0) is not installed in the onboarded Azure spoke VNET route table. Traffic that depends on the default route, including traffic destined for the internet through an egress transit, for on-premises networks through an S2C-connected transit, or for another spoke, may not be routed correctly from the Azure VNET. Workaround: Manually add the default route to the Azure route table. Contact Aviatrix Support for assistance.
AVX-73589	In some high-traffic environments using FQDN filtering, the traffic-filtering process may stall due to a deadlock. If the signal interrupts a thread that is already executing a non-reentrant function, the signal handler may attempt to acquire the same lock, causing a deadlock. Impact: Traffic processing on the gateway may stall until the service is restarted. Workaround: Restart the instance to continue processing traffic.
AVX-73629	When upgrading the Controller from version 8.0 to 8.1, the AM4.0 database migration may overwrite the VPC name field with incorrect data if old VPC records contain a pre-existing ‘name’ key with the gateway name. This causes affected VPC records to become unfindable via index lookups, potentially impacting Controller operations that reference those VPCs. Impact: VPC records may become unfindable after Controller upgrade Controller operations referencing affected VPCs may fail Any cloud service provider can be affected Workaround: Contact Aviatrix Support for assistance.
AVX-74055	In some environments running 8.0.30 or later builds, duplicate iptables mangle table MARK rules may remain on gateways during mapped Site-to-Cloud tunnel failover, gateway image upgrade, or rollback scenarios. These rules may accumulate due to incomplete cleanup during tunnel role transitions. Impact: No traffic impact has been observed. The issue only affects residual rule cleanup on the gateway. Workaround: No workaround is required. The extra rules do not affect traffic forwarding.
AVX-74226	CoPilot deployments and migrations may fail with “Unsupported instance size” errors when selecting valid instance types. The instance type validation incorrectly blocks supported sizes during CoPilot deployment or migration operations. Impact: CoPilot deployment or migration may fail when selecting certain valid instance types Error message “Unsupported instance size” is displayed even for supported sizes Workaround: Contact Aviatrix Support for assistance with CoPilot deployment using the affected instance types.
AVX-75000	Traffic loss may occur when gateways are upgraded from version 8.1.30 to 8.2.10. Impact: Traffic flowing through upgraded gateways may be disrupted Multiple gateways may be affected simultaneously Workaround: Schedule gateway upgrades during maintenance windows. Upgrade gateways one at a time in HA pairs to minimize impact. Contact Aviatrix Support for assistance.
AVX-75256	After upgrading the Aviatrix Controller from version 7.2.x to 8.0 or later, gateways with FQDN tags attached may no longer be visible in the Egress FQDN Gateway View tab. The list_fqdn_gateways API returns an empty list despite the gateways being present and properly associated with their FQDN tags. Impact: Egress FQDN-enabled gateways are not displayed in the Controller UI after upgrade The list_fqdn_gateways API returns an empty list Gateways remain operational and FQDN tag associations are intact Workaround: Contact Aviatrix Support for assistance.
AVX-75299	Due to a temporary Oracle Cloud Infrastructure (OCI) Marketplace partner agreement issue, new OCI gateway images cannot be published for this release. OCI gateway pointers have been reverted to previous versions to ensure stability. As a result, OCI gateways will not receive patched images as part of this release. Impact: OCI gateways will not receive the latest patched images in this release Customers using OCI gateways will remain on previous image versions until the OCI Marketplace issue is resolved Workaround: Contact Aviatrix Support for assistance with OCI gateway image updates.
AVX-75452	In Azure environments, when Distributed Cloud Firewall (DCF) Security Group Orchestration attaches a Network Security Group (NSG) to a subnet, the subnet name is changed to all lowercase. Although Azure resource names are generally case-insensitive, this modification causes issues with Infrastructure as Code tools such as Terraform, which treat resource names as case-sensitive. Terraform may flag affected subnets for replacement, potentially disrupting existing deployments. Impact: Subnet names in Azure are modified to lowercase when Security Group Orchestration attaches NSGs Terraform plans may show unexpected resource replacements for affected subnets Customer naming conventions in the cloud may be altered without consent Workaround: In Terraform, add a lifecycle block with ignore_changes for subnet_id (as well as id in the azurerm_subnet resource) to prevent forced resource replacement. Note that this workaround does not restore the original subnet name casing.
AVX-75582	In Azure environments, when a custom IAM policy blocks resource creation with a RequestDisallowedByPolicy error, the Aviatrix Controller unnecessarily retries the operation instead of failing immediately. Since this error requires manual policy changes to resolve, the repeated retries congest the Controller’s event handler, causing new gateway deployments to be delayed in reaching an operational state and spoke-to-transit attachments to fail. Impact: Gateway deployments may be significantly delayed due to unnecessary retry attempts Spoke-to-transit attachments may fail while gateways remain in a waiting state Controller event handler performance may be degraded Workaround: Update the Azure IAM policy to allow the required permissions for Aviatrix Controller resource operations before deploying new gateways.
AVX-75586	When using Terraform to create gateways and immediately attach them to transit gateways, a race condition can occur where the Terraform provider attempts to create the spoke-to-transit attachment before the gateway has fully transitioned to the “Up” state. The gateway creation API returns before the gateway is operationally ready, causing subsequent attachment operations to fail. Impact: Terraform-driven spoke-to-transit gateway attachments may fail intermittently Gateway creation appears successful but the gateway is not yet operationally ready Terraform apply operations may require re-running to complete successfully Workaround: Add a delay or polling mechanism in Terraform configurations between gateway creation and spoke-to-transit attachment resources. Use depends_on with a time_sleep resource to allow the gateway to reach the “Up” state before attempting attachment.
AVX-75607	Gateway launch may fail with a tls: bad certificate error when pulling container images. The Controller’s registry TTL eviction (garbage collection) may fire while images are being downloaded to the gateway, corrupting in-flight blob transfers. The gateway’s container initialization cannot complete, and a supporting certificate-management process on the gateway exits with code 125. Impact: Gateway creation fails with tls: bad certificate or unexpected EOF errors during container image pull The certificate-management process crash-loops with exit code 125 Manual intervention is required to recover Workaround: Restart the Controller’s application service to reset the registry state, then retry gateway creation. Contact Aviatrix Support for assistance.
AVX-75944	When migrating an existing Controller to a new Controller VM, a database migration issue can cause configuration changes to be applied to gateways too early during the migration process. Impact: Gateways with NAT configured may experience a temporary datapath disruption during Controller migration. Workaround: There is no workaround. Upgrade to a version that includes the fix (8.0.60, 8.1.30, 8.2.10, or 9.0.0). Contact Aviatrix Support for assistance.
AVX-76413	When the Controller’s state synchronization service starts up and finds gateways stored as “Down” in its internal state store, the controller reprograms the network as if those gateways are down, without allowing time for the gateways to connect and prove they are up. This can occur when the controller has previously lost connectivity to gateways (for example, during a transient network issue) and the service then restarts while the gateways themselves remain healthy and continue forwarding traffic. Impact: A temporary data plane disruption occurs while the controller has the gateways marked as down. The controller automatically detects the gateways are up and reprograms the network correctly immediately afterward. In a large-scale user deployment (~1,400 gateways), full recovery completed in approximately 6 minutes. The underlying behavior has existed for 4+ years and has been observed in a user environment only once. Workaround: Not applicable. The system recovers automatically, no user action required. Recovery typically completes within minutes (~6 min observed in a ~1,400-gateway deployment; smaller deployments recover faster).
AVX-76919	After a Controller or gateway upgrade, the gateway state synchronization service (avx-gw-state-sync) may crash if the gateway’s DNS configuration is not yet fully initialized at the time it is referenced. The DNS resolver configuration on the gateway can become corrupted during the upgrade. Impact: Hostname-based traffic on the gateway may stop resolving, which can cause the gateway to enter a push-config-Error state and prevent enforcement of Distributed Cloud Firewall (DCF) policies that rely on hostname matching. Egress traffic governed by hostname-based DCF rules with a default deny may be dropped until the issue is cleared. Workaround: SSH to the affected gateway and run sudo systemctl restart cloudx-gateway.service, or reboot the gateway. Restarting the avx-gw-state-sync service alone does not clear the issue. Upgrading to a release that contains the fix prevents the problem on subsequent upgrades. Contact Aviatrix Support if the issue persists.
AVX-77088	On Controller and gateway running 8.1.x or 8.2.x, editing legacy FQDN domain name filters can cause all FQDN filtering processes on the gateway to stop simultaneously. Gateway monitoring restarts the processes automatically, but a brief filtering outage may occur during the restart. Impact: FQDN filtering on the gateway may experience a short interruption when domain name filters are edited. Traffic that depends on FQDN filtering may be briefly affected until the filtering processes restart. Workaround: Schedule edits to legacy FQDN filters during a maintenance window. Contact Aviatrix Support for assistance.
AVX-77767	On Azure transit gateways with very large numbers of IPsec tunnels (3000+), all peerings to spoke gateways may go down under sustained high tunnel activity. The IKE daemon (charon) can enter a high-CPU state and reject new IKE_SA setup attempts. Diagnostic commands such as swanctl may hang in this state. Impact: All IPsec peerings on the affected Azure transit gateway can go down. The charon process may consume sustained high CPU. New IKE_SA setup is rejected for affected peers. IPsec diagnostic commands may hang. Workaround: Reboot the affected transit gateway to recover. Contact Aviatrix Support for guidance on tunnel-scale tuning for Azure transit gateways supporting very large tunnel counts.
AVX-79521	On Controller versions prior to 10.1.0, it is possible to onboard multiple Aviatrix access accounts that map to the same underlying cloud service provider (CSP) account. Because several Controller features assume a one-to-one relationship between an Aviatrix access account and a CSP account, duplicate access accounts can lead to unpredictable configuration and operational behavior. Duplicate is defined per CSP as follows: AWS (including AWS GovCloud and AWS China): same account number, for both IAM role and access/secret key authentication. Azure (including Azure Government and Azure China): same subscription. GCP: same project. OCI (including OCI Government): same tenancy and compartment combination. Alibaba: same account number. Starting in Controller 10.1.0, the Controller blocks new onboarding of duplicate access accounts across all supported CSPs. Existing duplicate access accounts continue to operate as-is and are not automatically removed. Impact: New duplicate access accounts can still be onboarded on Controller versions prior to 10.1.0. Environments that already have duplicate access accounts may see inconsistent behavior in features that assume a unique CSP account per Aviatrix access account. Workaround: Onboard only one Aviatrix access account per underlying CSP account. If duplicate access accounts have already been onboarded and are causing issues, contact Aviatrix Support for assistance with identifying and removing the duplicates.
AVX-80983	When Azure Security Group Management reads the current state of a security group rule before adding a new gateway’s IP address to it during gateway launch, an Azure API throttling response on that read can be misinterpreted as the rule not existing. In that case, the existing rule is deleted and a new rule is created instead of the existing rule being updated. Impact: Azure security group rules can be unexpectedly deleted and recreated during gateway launch when the Azure API throttles the read call. The delete-and-recreate sequence can result in a brief gap in security group coverage for the affected rule, or in duplicate rules if the sequence does not fully complete. Workaround: Contact Aviatrix Support if you observe unexpected security group rule changes on gateway launch in an Azure environment.
AVX-80977	A VPN user’s profile assignment could appear as N/A immediately after the user was attached to a profile through the API, until the user’s next reconnection. Impact: The user’s profile displays as N/A until the user’s next reconnection, even though the profile attachment succeeded. This can cause confusion when auditing or verifying profile-based access policies shortly after attachment. Workaround: Have the affected user reconnect to update the displayed profile assignment. Contact Aviatrix Support for assistance.
