Why XCloud doesn't work?

Russia, even regardless of the fact that I'm from Russia, I turned on vpn to just load the page with the game so that I could just press the "Play" button after I enter the site, I turned off the vpn and the game loaded normally

Where are you from? Your country.

Hello XO4Y, this is Manuela. I'm an Independent Advisor and community user like you, ready to assist with this.

I’m sorry to hear you’re having trouble when trying to use the cloud gaming feature. Let’s try to sort this out.

However, before that, I would like to ask:

May I know if you are using a VPN on your devices, or at router level?
Did you try using a custom DNS on your devices?

I would like to let you know that bypassing geographical restrictions to access features not available in your country can lead to a Microsoft account suspension.

I know this is not the outcome you expected, but we’re not able to assist if you’re using a VPN to access cloud gaming.

I highly appreciate your understanding.

it can’t be that it’s a provider, I sometimes even played quietly from the mobile Internet, the Internet that uses a PC and a phone has different providers, and black screens happened to me in 2 days, that is, if I use some new Internet, everything is ok , but if I want to run a second time using the same Internet with which I managed to log in from 1 time, 2 times I will have a black screen, even from a phone, I have a black screen, even the neighbor’s Internet is the same for me, I logged in the first time, but the second time I have a black screen, before I played normally for about 1 year
