I think they probably have aggressive firewall with a lot of false positives. I live in Switzerland and got blocked but tried a VPN to US and it worked. Although it is usually that I get blocked for using VPN.

But I'm not sure if it is about your IP or the whole country but I guess it the former. Who knows what the firewall god at Cloudflare does.

They block agressively. Not only based on IP adresses. If you visit the site with a privacy-focussed browser or in private mode they will also tell you your IP is blocked.

Thats weird. Fine from China (wonder what host they are using)
