I'm running Foobar2000 on my windows 10 laptop with the foo_upnp renderer-server plugin added. When using the Bubble app on my phone the Foobar renderer and server show up and I can play and browse the library on my home network. When I go to a different location and use a different network the Foobar renderer and server do not show up in the Bubble app. I can't figure out what the difference is between the 2 networks? And why the Foorbar server and renderer are not listed?
