Using app with minimserver

[janamdo]

Thanks
The audionet app (control point) is scanning the network and found the Marantz network receiver and also the tv
Minimserver is on PC connected with a wired networkcable and tv is also wired with a networkcable

Audionet app the control point is wireless and must sending a M-SEARCH to the minimserver
There are networksettings for the audionet app:
- Upnp search time out = 4 sec
- audionet-sync timeout = 2 sec
- internet protocol
Chanced some setting via help of audionet app, but no minimserver showing up on app

If i rescan or restart minim server on PC the minim server shows up in adionet app (Alive notification)
I do have a old smartphone : samsung S6

Minimserver is then blocked for M-SEARCH: fixing the routersetting?
