Server Unreachable

this week plex is not saying server unreachable. I believe it has to do with my account. If i create a new account it works fine, but my original account with plexpass, just says unreachable. I can’t see a way to fix this. I’ve uninstalled and re-installed PMS. Restarted the mac. No change.

MacOS 10.15.7

I also get “Not authorized - You do not have access to this server”
