Hello @Andre Marret ,
Thanks for posting your query on Microsoft QnA.
May I know for how long has the AKS cluster been stuck in Stopping state?
Did you try to stop and immediately trying to start the cluster? Repeatedly starting/stopping your cluster may result in errors. Once your cluster is stopped, you should wait 15-30 minutes before starting it up again.
Could you please check the current provisioning state of the AKS cluster from Azure Portal ?
Can you also please check the VMSS instances (If the cluster is in stopped state, you should not see any running instances under VMSS).
If you are still seeing the issue , please try to run the below command:
az resource update -n <aks cluster name> -g <rgname> --namespace Microsoft.ContainerService --resource-type ManagedClusters
If the issue still persists, kindly reach back to me and tag me. Thank you.
