Camunda Cloud self-managed troubleshooting guide

Hey cloud folk!

After a very good hint from @aivinog1 I am happy to share that I started off a GitHub repository for a Camunda Cloud self managed trouble shooting guide.

As of now the repository is still very empty since I am waiting for your troubles. :wink: If you have any suggestions what problems to cover in this guide open up an issue!

Thanks a lot for your collaboration!
