I use Crafty Controller for Minecraft. I have a server running at 192.168.50.16:25540. I want it to resolve to minecraft.example.com. I have Nginx Proxy Manager setup for my domain and can access it from inside my network, but it’d be nice to be able to use a domain instead.
NPM only has options for http and https, so is this even possible using NPM?
EDIT: this is for only internal access I have external access via tailscale.

No
Reverse proxies like you are talking about are only for http connections. For more information look at the OSI model. (The proxy is operating on the application layer while Minecraft is on the transport layer)
Instead use DNS to resolve the domain name to an IP. Better yet, just set a static IP.
There are minecraft reverse proxies, so, yes, a http proxy will not work, but the general idea is still viable and doable with very little effort.
Set up a few domains all resolving to one IP. Run itzg/minecraft-router and use that to proxy the traffic to different servers based on the domain.
Also, they don’t even need a reverse proxy, but just resolve the domain name to the IP (in the simple case of one domain name per I0). That can be accomplished by hosting their own dns server, editing the hosts file or just pointing a public dns record at the private ip address, which will only work in their network,l.
Thanks for the help. This is enough to get me started
You could also use nginx if you wanted; it’ll do arbitrary tcp data with the stream plugin.
NPM won’t help you here. As you said, it’s only for http. You will have to set up port forwarding in your router. But as far as I recall Minecraft changes its port with every game. So you could either change that in your router every time you start another game.
But it would be better (for security as well) to set up a VPN. Many routers actually have that built in.
That is, if your goal is to have your Minecraft server reachable through the internet.
For DNS you will need a Dynamic DNS service to let the name always point to your public IP. For this as well many routers have built-in functionality. Maybe even a preferred service.
