Fails to detect running upnp/dlna servers

[dikonov]

I have a notebook with running minidlna and Kodi v17.6 on Linux, which serves music via UPnP/DLNA. There are also 1) a TV with andoriod-based DLNA client and 2) a networked radio Prology WR-200 (UPnP media renderer) in the same home network. Both radio and TV can see and play content from the notebook using minidlna.

My phones (Jolla 1 and Jolla C) both running SFOS 2.2.0.29 () can see the Radio and stream music to its renderer (through the Jupii app). Donnie does detect the radio as a renderer. However, Donnie does not see the servers. Neither Kodi nor minidlna appear in the UPnP scan results!

Kodi has all UPnP service options ON. I turned off the firewall while testing. In a different home network I managed to detect another instance of Kodi v17.6 as a server but was unable to play any content. The server content browse page in Donnie remained empty or showed endless "wait" loop.

Port scan of the notebook:

Jolla Phone running Donnie is in the same subnet:

I switched minidlna tivo_discovery option from bonjour to the legacy beacon and it became visible to Donnie. Kodi is still invisible. Please, add the "bonjour" server discovery method!

Thanks for investigating and reporting this. Discovery is done in one of the used libraries, not by Donnie itself. Once I have more time I'll take a look at it.
