I can’t play chess today without vpn. What is happening?

The site isn't blocking players from countries, so your internet provider must be doing it

Ask your government. They are the ones doing it.

Ask your government. They are the ones doing it.
It's best not to ask them anything. They seem to get testy fairly quickly.

No, not blocking players:
