No connected servers?

This was the solution for me on a fresh Plex account with the “No Servers connected” issue.

Disable then re-enable remote access. Cheers.

This worked for me too, however my issue was slightly different in that users within my Plex Home could not see the server, but my admin account and remote non-Plex Home users could. It was a brand new server, fresh Debian 13 install. Restarted remote access fixed it though, thanks for the suggestion!
