School blocking vpn

How do i bypass school blocking vpns, they have some kinda data jammer so i cant use my data and their wifi blocks alot of websites and I’ve tried 10 vpns and only skyvpn works but the problem is that there is so many ads and an kinda untrusted vpn and it has very limited data, i want to use proton as its the best free vpn but it doesn’t connect ive tried all protocols and it still doesn’t work and in the settings of sky vpn i cannot see what protocol is uses does anyone know a fix for this

try openvpn with tcp… many wifi blocks udp connections… i have the same problem when connected to my company wifi no matter what udp isn‘t working… tcp works flawless

Your school doesn’t have a data jammer. They are illegal

It’s pretty trivial to block VPN access for someone who knows what they are doing

Try a VPN with an obfuscated server like mullvad
