I use a VPN setup on my own server everywhere (home, school, public wifi, etc). I am using AlgoVPN on an Ubuntu server. I have zero issues connecting at my house on PC, iOS, and Android. Once I use the school internet though, it is unable to connect. I am 100% sure it is the school doing this because it works on cellular connections and the school blocks many games. If anyone has any ideas on how to get around this that would be great. Many free VPNs work on the school
