Description of issue (in as much detail as possible)

I was following the doc Set up an Azure Arc-enabled Kubernetes cluster to run App Service, Functions, and Logic Apps (Preview) to deploy App Service to my Arc-enabled Kubernetes cluster, but failed at the last step "Create the App Service Kubernetes environment":

Internal server error occurred. Couldn't confirm connectivity to Arc-enabled cluster: /subscriptions/4dd59660-430d-4771-835d-b17a17362e07/resourceGroups/AzureArcTest/providers/Microsoft.Kubernetes/connectedClusters/my-cluster-1.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

All the steps before this one succeeded without any error messages, and I'm able to connect to my cluster using az connectedk8s proxy so I think it's connected to Azure.

My appservice-kube extension version is 0.1.7.

This looks to indicate that the Kubernetes cluster is no longer connected to Azure Arc. What is the status of the connected cluster? This can be found either through cli - az connectedk8s -n -g <Resource group> or via Azure Portal.

The command az connectedk8s show shows that the cluster is connected:

And now I tried the command again, it shows a different error:

Internal server error occurred. Error obtaining Arc information System.Exception: Extension not installed succesfully. ProvisioningState: "Failed". InstallState: "Failed". ErrorInfo: "".

Now I wonder if there's something I missed during the set up?

Some additional information

• The cluster is deploy via AKS on HCI
• I didn't deploy Log Analytic Workspace since it's not mandatory
