Some time ago I documented how I configured WireGuard on my OpenWrt router at home, to connect securely to my home network (and the Internet, really) from wherever I am. I feel safer connecting to public Wi-Fi this way, also abroad when it allows me to save extra roaming costs.
However, during my travels I sometimes come across networks which seem to block VPN connections, sometimes including my own personal WireGuard tunnel. For such cases I managed to tunnel my WireGuard connection over HTTPS, which is typically (far) less often blocked.
Are you sure you’re using an up to date browser? My server is using TLS 1.3 with x25519mlkem768. Most browsers should support this KEM already.
I’m using the latest firefox on the latest android (just tried it on chrome from the same phone and it loads fine)
