MA and Plex as Music Provider with a Yamaha MusicCast 20 Speaker (Connection issues)

[AdmiralRaccoon]

Hello,
I don´t want to open this as a bug, maybe it rather has something to do with my setup. Anyway, maybe someone ran into a similar problem:

When going to sleep, i´m starting a plex playlist for about 4 hours, but If I don´t fall asleep early, I notice that the playback stops before the timer ends. When looking into the log, I found the following. Anything I can do with Plex connection issues, as this Provider is still in Alpha state?

Here is the log, the Problems seems to start at 23:05.
I´m using The MA HassOS Addon and Plex is installed on a seperate Ubuntu VM.

Thank you for hints,
Philipp

Wondering why you mention Plex when the log indicates the player became unavailable?

[AdmiralRaccoon]

So the

"music_assistant_models.errors.PlayerCommandFailed: [Errno 104] Connection reset by peer"

means the MusicCast Device cuts the connection? Strange, to avoid connection issues, i connected this thing with wired LAN. Maybe i should run a ping log toight to see if the device gets unavailable.

There a number of connection problems shown in the log
