upnp renderer not discoverable

Hi all,

Just installed latest volumio on a rpi 3B+ with justboom dac, works great.
My only issue is with the upnp renderer, i just cannot get any client to find it.

Setup:
Mobile phone directly connected to the volumio wifi hotspot (so no router/L2 switch)
upmpdcli is listening on udp 1900 and the traffic is reaching the volumio box, however the renderer does not show up (tried a couple of android clients, no luck). Nothing obviously wrong in the logs.

Any hint?

Thank you.
