Plex Media Server version?
There is a problem with current versions of Android/Android TV apps and older versions of Plex Media Server. The Android apps are rejecting the security certificate from the server.
Users running Plex Media Server versions 1.18.x and 1.19.x are definitely affected. The problem may happen with other Plex Media Server versions (I don’t have a list of all affected releases).
The problem is visible in the Android client log: [FFmpeg] [ERROR] [tls @ 0xc35efba0] Peer certificate failed verification
Updating Plex Media Server to a current release fixes the problem.
If you cannot update Plex Media Server, such as some running Plex on WD & Netgear NAS, the workaround is to disable secure connections.
Plex Media Server: Settings → Network → Secure Connections = Disabled.
Android app: Settings → Advanced → Allow Insecure Connections = Always
Note: You will lose Plex Web access via app.plex.tv, which uses https, when you make this change. You will have to connect to your Plex server via http://nas_ip_address:32400/web (ex: http://192.168.1.2:32400/web ).
