Can´t connect via MacBookPro-Qobuz

But BubbleUPnP Server (and FireStream, for that matter) is just that---a UPnP Media Server. You still need something, the BubbleUPnP app, say, or mConnect, to act as a UPnP Control Point.

Maybe I'm misreading your posts but it seems like you need to read up on the whole UPnP architecture. See, for example, the Wikipedia article https://en.wikipedia.org/wiki/Universal_Plug_and_Play

I'll quote just a few lines from it

Generally a UPnP audio/video (AV) architecture consists of:

•     Control Point: a device that discovers Media Servers and Media Renderers, then connects them
  
•     Media Server: the server that stores content on the network to be accessed by Media Renderers
  
•     Media Renderer: a device that renders ('plays') content received from a Media Server.
