Cannot log in

I am unable to log into Forza whatsoever. I ALWAYS receive the following error message.

Error signing in

There was an error while signing you in with xbox. This account may not have an associated Xbox account. You may be able to resolve this by signing out and signing in again, or creating an xbox account - Sign out with The official website of the Forza franchise - Create an xbox account by signing in to (XBOX-caf53537-2e88-4884-9189-8a6ac052968c)

I already tried what it said but it did not help. The xBox mobile app works and I am logged into the app so I DEFINITELY have an xBox account but Forza seems to think that I do not.

I CANNOT EVEN submit a ticket because I cannot log into anything Forza related except this forums.
