This question already has an answer here:

I've been travelling for awhile and used a lot of Wifi access point lately. Several times my attempts to connect with VPN has been blocked (especially when using a "famous" one), and I've also noticed that some places even block TLS negotiations.

  1. How are they doing this?
  2. How can I circumvent it?

  • 2. is likely to be off-topic - it would be breaking a security system, without an educational understanding as the purpose. – Matthew Feb 20 '17 at 11:18
  • Actually, if they are disallowing TLS I would say they are breaking MY security system. – lash Feb 20 '17 at 16:12
  • Not really - you're using their network, so it's their rules. You aren't obliged to use it - you could get your own mobile internet connection, for example. – Matthew Feb 20 '17 at 16:14
