I wish I had written down the bug, but it’s possible that was the reason, because the client started saying “invalid login” while I was already logged in. The thing is, I then visited the website and had trouble logging in there too, it kept getting stuck on loading. I clicked “rest password” and it finally logged in 😅. Then I tried changing my password and at that point apple keychain’s autofill might’ve messed up and remembered a wrong one. I now reset it again and the client works.
