as you know Telegram, Facebook and also Twitter are block in Iran.
I using mikrotik Web-proxy which located in other country to using such as websites.
I can open Facebook and Twitter website without any problem but i can't open Telegram And YouTube Webpage.
I can see connections in mikrotik web-proxy connection section but there is no result in browser.
Why ? and there is other way to bypass this ban with mikrotik without PPTP connection?
