I could not sign in and have an error message repeatedly

" Oops! Something went wrong. Please try again in a moment. "

I’m having the same problem. I’ve tried signing into my existing GitHub-linked account, and also signing up for a new account with Google and with email. I’ve tried on both Firefox and Chrome. I get the same “Oops! Something went wrong. Please try again in a moment” message for all cases.

If you are unable to log in or keep getting “we cannot reach the server…” it may be that you have a duplicated account. To solve this issue you will need to write to support@freecodecamp.org.
