Hello BS MEA !
Thank you for posting on Microsoft Learn.
The Azure ML compute cluster that you are using, is either unavailable, deleted, or facing connectivity issues.
Since this issue started today and was working fine previously, consider the following troubleshooting steps:
Go to Azure ML Studio > Compute > Compute clusters. Check if the cluster is available, running, or deallocated. If the cluster is in a deleting or failed state, try recreating it.
If the cluster is Stopped or Deallocated, start it manually. If it’s in an Error state, check logs for more details.
You can run the following command to list available compute clusters:
az ml compute list --resource-group <your-resource-group> --workspace-name <your-ml-workspace>
