MX server not working after port forward

Postby NicoMacArthur » Sat Aug 03, 2019 9:49 am

Hello, I've been having some frustrating problems with trying to run a mxsim server. I have done everything correctly, to my knowledge. I downloaded the right version of the server.exe, set up the serverargs file, and port forwarded using UDP on port 19800. originally i was running it using hamachi (before i tried to port forward) , but now i trying to port forward to make it easier for friends to connect. My problem is, when i put my ip and port 19800 in https://www.canyouseeme.org (open port checker tool thingy) it says it cant see my service running. so of course my friends cant connect to it.

I really dont understand why, especially since my minecraft server works just fine right now (I'm obviously not running both mxsim and minecraft servers at the same time)

I even tried switching the port in serverargs and portforwarded and port-checked to a different port, but still no luck.
sorry if this is a problem that has already been discussed, couldn't find it on the fourums!

Do local connections work on 127.0.0.1?

Are you sure the server is running? It's either not running or the local software firewall is blocking UDP 19800.

"localhost" should be working in that case. Make sure the mxserver process is listed in task manager. If mxserver is running and you still can't connect using localhost on the same computer something is blocking the port.

I can connect through localhost just fine. Im guessing its some kind of networking thing that i cant see.

Actually i think its most likely something wrong on the server.exe side of things. I checked every firewall and saw nothing about the port being blocked
is there no server setup step i couldve missed? because im pretty sure filled out the serverargs correctly.

Have you port forwarded to your ip/using a static ip from your computer? Not all routers can forward to an unspecified ip.

Do you mean static local ip? Yea that never changes, its always 192.168.0.11

The public ip does change, but only when the router is reset, and like i said my minecraft server works just fine

Whoops. I misread your first post and thought you said localhost wasn't working. Probably something going wrong with the port forwarding in that case. Make sure you don't have both your router and modem doing NAT translation, you'd have to double forward if it was misconfigured like that. Also, the open port checker probably tries to make a TCP connection and won't see a UDP server.

Ok, i tried using a udp portchecker, and it still says "port closed"

Im pretty sure my modem and router are 1 unit, so how do i make sure they arent doing NAT translation?

There's usually a setting somewhere where it's either NAT on or off, or "nat or bridging".
