Woops I realized something and apologize.

Clearly the reset did work and the username is Administrator and the password is blank.

However the URL is invalid (I thought I was getting 401, it was a 404), and when I tried just admin.. I got a 401. So my bad

However, I still do not know the admin UI URL, if someone does please. I will keep trying the ones from this thread 🙂

Cheers!
