Hey there Cyclopropinon,
Yeah, I see what's happening here. The wurstforum.net domain was registered just 35 days ago, so some networks may categorize it as 'Newly Registered' and block it temporarily.
As for your suggestion about a GitHub proxy - it could potentially help in the short term, but honestly, this should sort itself out over time as the site ages and the network acknowledges it as safe. Just give it a little bit of time and maybe use a VPN for now.
