Gitlab login problem

Hello,

I`m trying to login on Gitlab after change my password sometimes, and Gitlab return 404 page with response “The page could not be found or you don’t have permission to view it.” and sometimes the response “Invalid Login or password” with the right login and password.

I also tried login with Github and Google but return “Sign-in failed because Email has already been taken.”.

Is it just happening to me?
Can someone help me please?

Thank you.

Does your account have MFA enabled.

Reconfirming your email address fixes the log-in 404 issue for your 2FA setup.
