I followed this forum topic! LINK
Received when tried to connect to XBOX games on pc and Windows RT tab.
I tought i didn’t have Media Feature PACK (For Windows N versions).
But then i remembered that it was installed.
So i did these things:
* Changed to the same at Regional Settings (Store, XBOX app and Windows)
* Changed Location, Time, Date to the SAME.
* Made Restart
* Signed in of my XBOX devices (XBOX 360 console). (Wrote Serial Number in XBOX homepage profile section).
