So, while this is not exactly a typical “self-hosting” question as many users might not be using domains, I would be curious if anyone else has any experience with this.

I have NGinx Proxy Manager installed on a vps and a few docker instances that host various services (wordpress, a gitlab, etc etc) that I have bound to specific ports (wordpress to port 80, gitlab to port 3000, to give made up arbitrary examples.)

I also have a domain and a few subdomains registered as Type A resource records that look like:
[www.]somedomain[.com]
[gitlab.]somedomain[.com]

The essence of the question: When I go to NGinx Proxy Manager and register a “Proxy Host” for the gitlab subdomain, like:

Domain: gitlab.somedomain.com
Scheme: http
Forward Hostname: <IP ADDRESS HERE>
Forward Port: 3000 (AKA the port gitlab is hosted on)

This works, but it comes with the drawback that the port number is then exposed in the url bar like so:

gitlab.somedomain.com:3000

So is there some way to fix this on the NGINX proxy manager side of things? Or is this a case where I’m doing this completely wrong and someone with web-dev experience can help me see the light. While it’s not a huge hindrance to my use-case, it would still be nice to understand how this is supposed to work so that I can host more services myself that require domain names without having to shell out for isolated IPs. So if I hosted a lemmy or kbin, for example, I could actually configure it to use my subdomains correctly.

    Edit: ignore everything, just realized it’s all running on a VPS. In that case, change WordPress off port 80. NPM needs 80 and 443.

    ~~Assuming you have port forwarding on your router set up with 80 and 443 being forwarded to the local IP of the machine hosting NPM…

    Another problem you might run into is NAT Loopback, but it all depends on your router.

    So you type lemmy.domain.com (no port), it goes to DNS which points it to your home IP, it goes back through your router and gets forwarded to NPM, and NPM does the handling of which IP:PORT to serve up.

    I have adguard home doing all of my DNS so to get around the NAT loopback problem I have custom DNS rewrite rules. It’s very simple in my case: *.domain.com gets directed to the local IP of NPM.

    When I’m outside my home network, NAT loopback is no longer a problem and things work as they should.

    Sorry for rambling, just reciting some general overview stuff that I’ve learned along the way.~~
