Plex User Account - Login and get "Credentials Have Expired, please sign in again"

This keeps happening to me, and I have searched the forum for this already and seen one response pointing out that the cause is a bad character used in my username before some checks were setup on the back end.
That is all well and good, but I need to get this remediated ASAP please. How do I go about that?

I think you’re having the same problem the rest of us are having: https://forums.plex.tv/discussion/292802/failed-login-loop-invalid-expired-credentials#latest

I think plex was hacked again.




Same here…

Frustrated

It’s a server that keeps keeling over, apparently.
