Loss of websocket connection to Plex causes a permanent hang.

[InsertDisc]

If Plex restarts and closes the websocket connection there is no attempt to reestablish the connection.

[RemiRigal]

When Plex closes the websocket connection you should have the following logs:

[WARNING] Lost connection to the Plex server
[INFO] Trying to restore the connection to the Plex server...

If not, do you have any logs that could indicate a failure ?

[InsertDisc]

I was getting [Warning] Plex closed the websocket connection.

I don't have exact logs to copy as I guess you lose them on a PAL restart.

After restarting Plex I would have to restart PAL as well to restore the connection.

Turns out the issue was a bit deeper. Running maintenance on Plex, having PAL listening and scanning with PMM was causing the server to crash.

I've separated the schedules a bit better to avoid the problem in the future. However, if somebody has a script to restore Plex after a crashed state, the issue with PAL reconnecting would probably still arise. Not something that should happen often, but it's still something that can.

Thank you for your great communication.
