I set up a new Plex server with Docker. Everything works fine except android 'amp and 'dash. They see the server but no libraries. ChatGPT talked me through debugging and said. Beta seems to work for 'amp, but I can’t find a beta for 'dash.
Android Plex Dash fails to connect because it rejects the Plex server’s HTTPS certificate.
Dash discovers the server name but shows no libraries or activity. The server logs repeatedly show:
CERT: incomplete TLS handshake … tlsv1 alert unknown ca
Affected: Dash 2.1.1 and Plexamp 4.12.4 on Android. Plex Web on the same phone and Dash on iPad work.
Plex acknowledged a Plexamp compatibility issue following changes to Let’s Encrypt’s root/intermediate certificates. Installing the newer Plexamp beta fixed Plexamp for you. Dash appears to have the same issue, though that hasn’t been officially confirmed.
