Commit searching dont Work

Hello. Im using Gitlab CE 16.3 on my own server. But now the searching a commit dont work.
All my commits are Listet in my own scm system but i cant search the commits in gitlab.
The commit is in gitlab and if i copy the commit number from gitlab and search in gitlab then gitlab post: “we cant find project with: xxxxx”

Searching for commits always worked. Since version 16.3 this is no longer possible. This is the most important function for me. Can someone tell me why this doesn’t work anymore? I install all updates exactly as specified by the manufacturer.

I have already implemented the tips from the forum. Unfortunately I can’t search.
Thanks in advance.
