I’m trying to set up a domain to more easily access my services on my home network, using a vanity URL instead of IP:port. With my current setup, my browser is not able to see the server (‘we can’t connect to the server’ at e.g. plex.mydomain.xyz).

I registered the domain through Cloudflare. In Cloudflare, I set up my DNS records (A - mydomain.xyz - content = 192.168.x.x; A - www; CNAME - *), and got my API token. Nginx is running in Docker (as are the services I am trying to access), using the jc21 container and their docker compose template. I used the API token to generate an SSL certificate in NPM with *.mydomain.xyz as the domain, then added a proxy host using the URL mentioned above as the Domain Name, the IP of the server that’s running all my containers for the forward hostname/IP, and the appropriate port for forward port. Then in the SSL tab told it to force SSL and HTTP/2.

I’m not sure what I’m doing incorrectly, the only thing I have running that might interfere with the network service is a PiHole, and it appears to be sending the request on. Also tried using localhost (127.0.0.1) to no avail. I’ve seen some others say they had to restart NPM a few times, so I’ve tried that as well. Thanks for any help!

*Edit: My router had DNS rebind protection enabled which was blocking the local address. I discovered this by using NSLOOKUP on my home network, where I got a ‘No internal type for both IPv4…’ error (in Windows command prompt) and outside my home network, where it resolved correctly. Thanks to those who commented, appreciate your time.

    Nginx is running in Docker

    Are you launching the container with the correct ports exposed? You generally cannot make connections into a container from the outside unless you explicitly tell Docker that you want it to allow that to happen… i.e. assuming you want a simple one-to-one mapping for HTTP and HTTPS standard ports are you passing something like -p 80:80 -p 443:443 to docker run on the command line, adding the appropriate ports in your compose file, or doing something similar with another tool for bringing the container up?
