iTunes not signing me in.

I sign into iTunes, on multiple systems, (old mac pro, new mac studio) using my store credentials (not my cloud credentials) and it doesn't error, but doesn't sign me in.

I go up to account > sign in over and over.. tried my icloud login creds... nope.. made a new login... nope...

This is on multiple systems so I am guessing my account is screwed up at Apple.

I cannot update my iTunes Match to sync new music up to the cloud. If this won't work anymore, I will cancel iTunes Match and use Plex.
