The server is unreachable
i've got a peculiar problem that has just occured after years to smooth sailing.
"The server "NIKINOO" is unreachable. Make sure it's running, double check your network, and try again."
i am loading plex web from the pi itself (ie NOT from app.plex.tv), so from what i can see plex web is running, but it's saying it can't see the server?
the required port (32400) is still open and pointing to the correct local IP of the pi. (other services are still operating correctly - radarr, sonarr, etc etc).
