[PROBLEM] upnp renderer disappears

[cereyanlimusiki]

Hello all

hope you are healthy and fine.

I am on 6.7.1 and it is connected my homenetwork over wifi.

I am trying to use tidal with 

I enabled upnp renderer from audio config and saved my tidal id and password and I am using mconnect on iOS but mconnect never find moode upnp renderer

I used a tool on mac UPnP analyzer to see wherther renderer is discovered on my network 

If I restart renderer it shows up UPnP analyzer browser for a second and then disapears. I have an another device with UPnP enabled and this show all the times on UPnP analyzer browser so I assume it is not a router or network issue 

What other troubleshooting steps I can take ?

Thanks
