long story short had issues a little while ago with a different docker tried to update and failed miserably, got it to come back but no remote connection, tried a bunch of stuff, now on plex offical docker and still no go im beyond lost…
If it’s open and shows success via the link above, stop plex, go to the Cache directory in the plex media server folder, is there a certificate.p12 file? If so, rename it certificate.p12.old and start plex back up. It should download cert-v2.p12. Test remote access.
