volumio hotspot and DLNA server


I’m a member of a swimming union. Swimming is fun, but everything is more fun with music, so I thought why not having a rapspi and volumio connected to the stereo equipment of the bath and turn it to loud :smiley:

Now my question. I managed to connect to the volumio hotspot which was super easy! Great work btw.

But BubbleUPnP can’t find volumio’s dlna server anymore. It used to find it successfully when volumio was connected to my home wlan.
Is the DLNA Server not started when the hotspot is active?

Can I somehow start it?
