Where to find Gitlab Admin Credentials on the command line using Red Hat

Hi everyone,

I recently installed Gitlab on a Red Hat machine, and I can access the admin page via the UI. However, I tried logging using the admin account with username: root and password: root as well. Unfortunately, I am unable to log int. I followed the steps indicated here ( Rails console. I reset the password accordingly, but continue to get an error message stating that username or password are invalid.
Again, this would be my first time logging into app.

Any clue what is gong on?
