No Gitlab Project - No Data

I use VSCode and this extension for my Slef hosted Gitlab CE. https://dev.it-open.at I changed the URL in the Settings. and gave a URL and PAT via the command (Gitlab: Set gitlab Personal Access Token)

Restarted! I dont see any Data. And when I try to make a new Issue it tells me that this is not a Gitlab Project. Is there anything I can do to get more Information about whats the Problem?
