My Squeezebox times out after 20s (notification message)

I am running OH 4.1.0M3 on a windows PC with the Squeezelite-X app installed. Now when running this simple rule

configuration: {}
triggers: []
conditions: []
actions:
  - inputs: {}
    id: "1"
    configuration:
      volume: 50
      sink: squeezebox:squeezeboxplayer:23787f5cb4
      sound: Rain1.mp3
    type: media.PlayAction

the player stops after 20s. I tried several locally stored mp3 files but all have the same issue.
Here the debug-log:

There is a callback URL which is in my case empty (default). Could someone give me some hints how to solve this problem?

Thanks

You can set the notification timeout in the thing.
If you play a sound directly from openhab it’s a notification.
try playing a favorite from your squeezebox server.

configuration:
   notificationTimeout: 20

Oh many thanks. I had no idea that this timeout can be set in thing :slight_smile:

But for some reason the notification is shown in the player when running the rule. Now I do have the problem that the sound file is not starting (playing) anything! When running a radio station directly from the favorites it works.
Here a log:

I also manually changed the volume etc. but it simply does not play.

Is this the right mp3 file?
I did a test now.
my file is

http://192.168.0.9:8080/audio/714da8ef-af78-4c35-a8ef-43d03df353b1.wav

My callback url is ‘http://192.168.0.9:8080’ (my openhab)
Maybe try to add your openhab ip…

Thanks now it works!
