Important

If your Azure Stack Hub instance is behind by more than two updates, it's considered out of compliance. You must update to at least the minimum supported version to receive support.

Compute

Azure Kubernetes Service on Azure Stack Hub

  • Applicable: This issue applies to release 2311 and later.
  • Cause: Azure Kubernetes Service on Azure Stack Hub, currently in preview, is being discontinued and will not be released to general availability. If you try to register a new subscription to the Microsoft.Containerservice resource provider, the registration stays in the Registering state. If you try to create a new managed Kubernetes cluster or access existing managed Kubernetes clusters, you might see the raining cloud error screen.
  • Remediation: Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Common.

Shutdown using Start-AzsCryptoWipe does not work

  • Applicable: This issue applies to release 2311.
  • Cause: In some cases when you run the Start-AzsCryptoWipe command to shut down Azure Stack Hub, one of the physical machines is not powered off.
  • Remediation: If you see that any physical machine is not powered down, you must turn off that machine through the Baseboard Management Controller (BMC).
  • Occurrence: Common.

Portal

  • Applicable: This issue applies to release 2311.
  • Cause: In the Azure Stack Hub user portal, under the Virtual Networks section, there are three new options for virtual networks: DNS Servers, Flow Timeout, and BGP community string. You can successfully modify the DNS configuration using the DNS Servers option. However, attempts to use the Flow Timeout and BGP community string options result in a failure within the portal notifications. No changes are made to the underlying services; the errors are only in the portal.
  • Remediation: Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Common.

Resource providers

Incorrect rotation status after secret rotation of resource provider certificates

  • Applicable: This issue applies to all Azure Stack Hub add-on resource providers.
  • Cause: After secret rotation, the rotation state shows as "in progress" even though the rotation completed successfully, the provisioning state shows "successful," and the expiration date is updated.
  • Remediation: None. No impact to your system or workloads.
  • Occurrence: All supported versions of Azure Stack Hub.

App Service

Incorrect rotation status after secret rotation of resource provider certificates

  • Applicable: This issue applies to all Azure Stack Hub add-on resource providers.
  • Cause: After secret rotation, the rotation state shows as "in progress" even though the rotation completed successfully, the provisioning state shows "successful," and the expiration date is updated.
  • Remediation: None. No impact to your system or workloads.
  • Occurrence: All supported versions of Azure Stack Hub.

Portal

Incorrect reporting of node CPU cores in the admin portal

  • Applicable: This issue applies to release 2301.
  • Cause: The number of cores reported in the Azure Stack Hub admin portal in the cluster Nodes Capacity window is incorrect. This is cosmetic and an issue with a change in 2301 with respect to how the Fabric Resource Provider gets this information. This impacts both new deployments and existing stamps updating to 2301, but doesn't affect operation of the stamp or any workload deployments.
  • Remediation: Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Minor portal issue that occurs consistently.

App Service

Incorrect rotation status after secret rotation of resource provider certificates

  • Applicable: This issue applies to all Azure Stack Hub add-on resource providers.
  • Cause: After secret rotation, the rotation state shows as "in progress" even though the rotation completed successfully, the provisioning state shows "successful," and the expiration date is updated.
  • Remediation: None. No impact to your system or workloads.
  • Occurrence: All supported versions of Azure Stack Hub.
