Have you just installed the Pterodactyl control panel on your EUGH VPS, VDS or dedicated server, gone to install Rust and found it hanging on installing Umod?

The Cause Of The Issue?
Simply github rejects the connection if its from a direct IP with no source SSL certificate, Reinstalling Pterodactyl and running it on a domain and having my machines on FQDN this has resolved this issue.
