Pangolin (lemmy.world)

So, I'm trying to get pangolin up and running.

What I have: Ubuntu server running in proxmox, docker running on that Ubuntu, dynamic IP, duckdns in docker to counter that, domain name

What I did: installed pangolin with the installation script, said yes to crowdsec because it looked like the safest option (over time) even if I don't know what it is/does, set a CNAME from pangolin.mydomain.com to my.duckdns.org, set a port forward for ports 80 and 443 on TCP and for port 51520 on UDP

What is happening: well, fairly, not much. If I test it from outside the network, I get a connection refused. If I test it locally (in portainer click on the 443 or 80 port) I get page not found

What I want: I want it to just work without a hastle and hope one of you can help me out here, cause I'm starting to lose my mind

As a sanity check, I just completed the same setup that you described (Ubuntu Server 24.04 running in a Proxmox VM, Domain name pointing to a CNAME that points to the Dynamic IP, using the installer script, enabled CrowdSec, etc.), and everything worked out of the box. A couple of things I noticed that would also be worth checking now that I'm more familiar with this specific setup are:

  • In the config/config.yml file, verify that the dashboard_url is set to the FQDN of the full URL (e.g. pangolin.mydomain.com), and that the base_domain is set to the root/apex domain (e.g. mydomain.com).
  • Double check those DNS records. As the haiku goes: it's not DNS, it couldn't be DNS, it was DNS. dig pangolin.mydomain.com or dig @1.1.1.1 pangolin.mydomain.com should show the CNAME that points to the A record.
  • A 404 page not found error is normal when connecting to the IP address directly rather than using the domain name. I was successfully able to access the dashboard using the FQDN from a local and external network. Depending on your network, you might want to set up a local DNS record that points to the internal IP address as well (though this should be optional in most cases to my knowledge).

I hope that helps!
