Transfer play to sonos speakers fails

Issue description:

Playback on device works fine. Go to select a different device, list populates with all speakers. Select a sonos speaker, the track stops playing, the play button has a spinning circle which eventually stops. Switching playback back to the local device allows the song to restart playing.

Phone is a Pixel 9XL, running Android v.15
LAN is 192.168.1.x where the phone and sonos speakers are connected
Jellyfin server is on 192.168.20.20

Tailscale is used as VPN to the jellyfin (so that it works out of the house) but there is currently a route from 192.168.1.x to 192.168.20.20

Since you are connected via tailscale the connection to Jellyfin is fully unknown from your Sonos devices that’s normal.
You can enable proxy mode in Symfonium renderer settings for those Sonos devices.
