All other devops project releases are failing also for same reason.

Any help to debug appreciated

Answer 1

well, this clearly has nothing to do with the release if all the releases are failing. Something happened to your cluster or to your service endpoint

You would need to check if you can connect to the cluster endpoint manually with powershell, for example (connect-servicefabricluster or something along those lines).

Answer 2

misunderstanding of built in release task. guess cluster was created by DevOps project create and not release task as I thought.
