Okay so I think I found a solution for me, not sure if this is everyone else, but worth a try!
What was happening
As per my other thread: "No connections available for {server}" - Library not visible on Android - Works on web
It seems that the connections to the server from were timing out, but when going via plex.direct and the directory. For whatever reason (maybe domains, maybe SSL) this meant that some clients (all Android-based, either phones or TVs) could not connect or see the server.
More details in that thread.
My server set up
My server is set up with both a custom domain and a SSL certificate. This is running off a local server on my home network. Up until the app changes early last year, everything was working fine.
So, static IP, non standard port forwarded to my server over the normal PMS port.
What seems to have worked
In Plex Network settings, I had both the https and http versions of my domain and port under the Custom server access URLs field. So it looked like:
https://plex.domain:12345,http://plex.domain.com:12345
I decided on a whim to add the direct IP address also to this list. So it became:
https://plex.domain:12345,http://plex.domain.com:12345,http://123.123.123.123:12345
This seems to have fixed the issue across all previous clients and they can now connect across Android.
See if this works for you.
