I have recently been finding myself on a network (cellular) that blocks access to VPN. I have tried Wireguard on multiple ports using IVPN and Windscribe with no luck. Similarly tried OpenVPN and IKEv2.
I also tried using Windscribe’s “stealth” protocol and IVPN’s obfuscation protocol but again with no luck.
I refuse to rawdog the internet like that and was hoping to get advice on how to work around that nonsense.
I am on iOS if that matters.
Usually openvpn via tls port 443 is the least blocked.
I also had luck with UDP on port 123. On some public WiFi networks I could even connect to internet that way without agreeing to ToS on “login page”.
