Error when the jellyfin server is listening on a subpath

[oscmedgon]

I'm encountering an error when using the plugin: My environment is:

• Jellyfin server v10.9.10 listening on http://server_ip:server_port/jelly
• Volumio v3.742 with plugin v1.1.1 on a different device pointing to the jellyfin base path (http://server_ip:server_port/jelly)

Expected behavior

When playing music the audio streams are requested to the Jellyfin server on the specified path.

Current behavior

The music stream URL does not contain the path leading to an error in the playback.

The received error in the WS is (The original error shows the IP and port but have ben replaced to report the issue):

42["pushToastMessage",{"type":"error","title":"Error","message":"Failed to decode http://server_ip:server_port/Audio/song_id/stream.flac?static=true&mediaSourceId=song_id&t.flac"}]

Updating the shown URL by adding the path leads to the actual stream which works.
