AKS cannot be deleted from the Azure UI due to an error.

When attempting to delete the AKS using the Azure portal UI, the error message "This Cluster is in failed state" appears, and a notification is received when trying to stop AKS.
"failed to terminate the 'akspoc' Kubernetes service. Error: Since deletion was issued on "akspoc," "Stopping" operation on "akspoc" could not be completed. Once deletion has begun, the only operation that is permitted is deletion". I had to wait two days to know how the deletion was going, but there was no progress.

How then can I delete an Azure Kubernetes service the most efficient manner possible?

    Please try to reconcile the cluster, then delete it.

    Try this via Azure CLI -

    az extension add -n aks-preview
    az aks update -n clustername -g clusterresourcegroup
    az aks delete -n clustername -g resourcegroup --debug

    if you still cant delete please paste your debug log.

    It was discovered that a some of my existing nsgs belonged to the default aks resource group, blocking deletion. My problem was fixed by removing those from the RG and running the delete command from the Azure cli. thank you all.
