    Can someone explain from a technical standpoint how they can block OpenVPN running on port 443? my admittedly limited understanding is that port 443 is the common port for https. If they blocked that port wouldn’t that mean that they would be blocking nearly the entire internet?

      You can analyze the traffic, detect common patterns and also detect source of the request. Russian IT specialists are now using very complex solutions to come around the block which work a lot like MITM attacks.
