Describe the Bug

I just brought up a new Hertzner VPS and installed pangolin on it. I can reach the dashboard just fine, but when I am trying to install a site the VM that I am installing to will not connect. I have verified that the Hetzner firewall allows 80, 443, 51820, 21820 as well as my firewall allows it. Here is what happens after I run newt with the id and secret and endpoint:
