Issue description

What happened and what you expected instead:
On 8/26 in the afternoon I suddenly lost connection with my Plex server for unclear reasons. When I returned home my computer had installed a Windows update and I rebooted the computer. The computer booted normally and I relaunched the Plex server. This worked locally and was streaming on other devices within the house. I attempted to play music through Symfonium and received the same sync error. I restarted my phone after closing and then force closing and restarting the app, which also did not help. However it still will not connect. I have checked the Plex settings and it appears to still be able to connect to the outside internet. The Plex app still works and will stream from the same library.

The exact steps needed to reproduce the issue:
At this time any time I attempt to reconnect the Plex server through Symfonium, it fails. (Logs submitted at 0650 CDT on 8/27)

Whether it happens every time or only under certain conditions: every time

The approximate time when you reproduced it for the uploaded logs: as above

Your device, Android version, and Symfonium version Samsung Galaxy 23 ultra, Android 16, version 15.0.1

The media provider and server version involved, when relevant
The playback method or output involved, such as the local device…: Plex server, (most recent update), any output (no connection)

Seems your server now reports an invalid https certificate.

You can try to add again a new connection to the server, Symfonium can ignore the invalid certificates on initial add if forced, but will always refuse to ignore it if it was validated before for security reasons.

Would this mean completely removing Plex as a source from the app and then re-adding it? I worry I would lose my playlists and etc.

Everything should be synced on the server with Plex so there’s nothing to be lost if you did not made mistake before.

And that’s why I told you to add a new one not replace yet.
