Stream to Sony CMT hifi (DLNA) from KODI/RPI2

Hi, my Sony CMT hifi finds my KODI server (through WiFi), but once I try to connect it says: "Can't connect". Standard W10 PC with Windows Media Player streams just fine to the Sony CMT (can browse and play all albums, slow browsing but working, etc.). Can I tweak anything on my UPNP/DLNA settings on my KODI/LE/RPI2 setup to make this work? External HDD on RPI2 has all the albums, so.... Thx!

Anyone?
