Serviio and XBOX One

Hello!

First of all, thank you for this amazing program.

However, i have a problem with Serviio on Xbox one.
I cannot always connect Xbox one to Serviio. Sometimes Serviio is visible in the Xbox One's media player and i can play videos, but sometimes (most of the time) Serviio isn't on the media player list.
Serviio says Xbox One is inactive

Does anybody else have a problem? How can i fix this?

Oh yeah and i have Windows 10 pc.

Edit 1. I installed the Serviio again and now there is no my Xbox in the list at all. Dammit!

Edit 2. So i reset my router and now i can see Xbox in Serviio console and it's green, so everything should be ok, but still i can't see Serviio in Xbox media player.

Might be some UDP traffic is not coming through your router.

My router is Cisco EPC3928.
