My Synoloy-NAS use a fixed IP-Adress (192.168.0.x). In addition i am using the package "docker" on my Synology-NAS.
Everytime when i start the package "docker", a virtual bridge with the IP 172.17.0.x will automatically be 'activated'. And from this moment on, Subsonic / Sonos will communicate via the IP 172.17.0.x., and this fails.
This Error-Code is in the LOG-FileINFO SonosServiceRegistration Enabling Sonos music service, using Sonos controller IP 192.168.0.x, SID 242, and Subsonic URL
http://172.17.0.1:4040/ws/SonosWARN SonosService
Failed to enable/disable music service in Sonos controller 192.168.0.x: org.apache.http.client.HttpResponseException: Bad Request
So i have to force Subsonic / Sonos to use the fixed NAS-IP-Adress (192.168.0.x) and not the 172.17.0.x.
