I got a problem with steam, that it wouldn’t load UI and acts strangely on login screen without using VPN.
When I open steam it says loading user data, then it throws me on login window and 5 - 6 seconds after it starts to load main page (which is obviously won’t load)
Since you’ve mentioned Cyrillic and if you’re still inside Russia - that probably means your provider is blocking Steam (maybe not deliberately but by accident, РОСКОМНАДЗОР have done that multiple times in the past as far as i’ve read)
Maybe you’re right and its RKN’s fault (they’re always blocking smth with no reason and forget about it). But it all started on one day. Just boom and no steam
If VPN won’t work one day - i suggest you to learn how to do full Tor network through webtunnel bridge, which is so far undetectable by ISP / censors…or lokinet, it seems to be faster.
In places like China, Russia, Iran - it’s a mandatory survival skill.
