If you enable the custom location and cluster connect features on your Azure Arc connected AKS on Azure Stack HCI cluster, you may see the following error:
Error while updating agents for enabling features. Please run "kubectl get pods -n azure-arc" to check the pods in case of timeout error. Error: Error: UPGRADE FAILED: timed out waiting for the condition
This is a known issue with the September release and is fixed in the October release. New AKS on Azure Stack HCI clusters created using the October release and connected to Arc using Enable-AksHciArcConnection do not experience this issue. Update your AKS on Azure Stack HCI deployment to the October release and then reconnect your existing clusters to Arc for a workaround to this issue.
