at my school, I was able to get away with using a Chrome extension called UltraSurf. I was able to search these forums, as well as check discord, playing blockland through Steam is possible, but only offline since it runs in Chrome.
Now it hardly works at all, I think all Macbooks have this OpenDNS Umbrella Roaming Client thing that I guess... blocks all proxies... I always get an error that UltraSurf can't connect, and I have to preform diagnostics, all that does is checks if you have an internet connection, and if UltraSurf can connect to a stable proxy address, it may use HTTP IPs I'm not sure...
