MinimServer (0.8.3f, Raspbian) not discovered by BubbleUPnP when VPN is on

[brencer]

I should add that when I browse my Minimserver library via BubbleUPnP with the VPN turned off, and make a queue of music, I'm still able to play that queue even after I turn the VPN back on and I'm unable to see or browse the library anymore. Looking at the info of the playing content I can see my local IP to the Raspberry in the stream url. So the problem only seems to affect the discovery of the Minimserver, not content access.
