Reboot your rpi and phone ?

It answers to discovery but Symfonium can’t connect to the advertised address and port.

Just rebooted, fresh logs at snippet_upnp_2. Seems to be in the same state though sadly

Check the RPI logs, your wifi router, your connections.

The UPNP answer says to connect to http://192.168.50.250:49152

But the phone can’t connect to that ip and port

There’s nothing I can do from Symfonium side.

Thanks for the support, it must be somewhere else in the network then.

Solved it. There’s a wireless network setting on Android under Privacy that randomizes your MAC address, when that’s enabled you can’t see / connect to any other wireless network devices. Disabling it allows you to see and connect to other devices on the network
