did you resolve this issue ? I have the same problem 
Here 's is my config :
-OSMC running Kodi 17.6 on raspberry pi 3
-dlna server running on a tv box on the same network subnet.
i configured “setting/services/UpnP DLNA” with “allow remote control via UPnP” checked. I also tried to configure IP address of dlna server… Still in error.

Marc
