I followed this guide: https://notthebe.ee/blog/easy-ssl-in-homelab-dns01/
But my Nginx Proxy Manager is running on a VPS that is connected to my local network through a WireGuard tunnel. Could that be an issue? I don’t know why it’s not working?
My NPM is also accessible to the local IP of my homeserver on which WireGuard is running.
NPM should serve as both, but only issuing SSL certificates for my local network is the issue. Have you taken a look at the tutorial I’ve linked in the original post?
And what do you mean with the port I’ve exposed? Exposed where? NPM uses port 81.
Yeah I looked at tutorial. Port 81 is only for management (NPM admin gui). Then you have your traffic ports for proxy services. Those would be 80 and 443 normally. You would need to expose those ports to the Internet if you want to access NPM/proxy your service. Port 81 shouldn’t be exposed on your public interface make sure it isn’t or at least have firewall rule to allow only local network (ideally management network/vlan)
Ah I see. As I’ve said the proxy is working for my domain and is available from the internet. So that shouldn’t be an issue…
This is the output of the openssl command:
