The ISP might be running TLS SNI blacklisting. When you establish a secure HTTPS connection, TLS will send the website you’re connecting to in plain text.

Work is being done here to encrypt the SNI, and you currently can do it in Firefox, but only to websites that are also using Cloudflare (or have implemented eSNI, which is very little outside of CF).

Otherwise, if they do IP blacklisting, the only thing you could do is use a VPN.

ok but why websites are working fine when i started using google DNS 8.8.8.8 on my other browser and i have turned on encrypted SNI using this website https://www.cloudflare.com/ssl/encrypted-sni/

that site is not working anymore on google dns too

is there anyway around these errors?
from these censorships from ISP and countries?

right now cloudflare DNS is connecting me to server located in ATH still unable to load websites
