I am a windows user, using the edge browser.
I just checked through firefox and chrome without extensions, but the same problem.
It's slow, but it works with vpn (I don't know why I didn't check it earlier).
I'm from Russia, and I think the problem lies in blocking foreign services. Although it may be a matter of the provider.
Actually, from the very beginning of the post, I had no goal to solve this problem.
I just wanted to draw the attention of developers to cross-platform, because I consider it a good practice, even if the project is only in demo.
P.S. I was probably too lazy to solve the problem, so I just skipped such games.
