Subsonic not connecting to a Sonos

[lemonyelow1]

This WAS working, but now it's not. I'm using the Android S1 app - which DOES seem to OK subsonic as a "service" that they support.... Yes, my PC, phone and my Sonos are on the same wifi network, and I just created a new (non admin) user using your web interface and all went well.... UNTIL I entered the same User & Psw on the phone, and Sonos' app reported that it could not connect. Any thoughts? THANKS.
