When I try any operation with git in IDEA (pull, push, clone etc.), I receive message:
Update failed
unable to access 'https:...git/': The requested URL returned error: 500
But when I try it with terminal, it works. It's about all gitlab projects. It looks like something wrong with my IDEA, but I not shure. My Pycharm-projects in same gitlab directory works fine.
There is HTTP 500 response, this is most likely something on the server-side. There is known issue with random 500 errors returned by GitLab - e.g. https://gitlab.com/gitlab-org/gitlab-foss/-/issues/66449
If not that exact issue (make sure you use the version that includes the fix), there might be other similar issues.

There is error in Idea when saved password is incorrect.
Clearing KeePass DB
(you can read how to do it in official documentation to Idea there https://www.jetbrains.com/help/idea/using-git-integration.html#set-passwords-for-git-remotes)
and entering password anew fixed this error for me.
