[aur-general] ssh access on port 443

Hi My firewall is restrictive and won't allow outgoing traffic on tcp/22. github.com and gitlab.com both provide alternative addresses that use tcp/443. Is there something like this for AUR? I know I can just use a general proxy, but I don't have access to another network or computer to host my own, and all public VPNs and proxies that work in this network are slow. Thanks eNV25
