Need help w/ running a server on my PC

[marsh fjord]

Hi, I've been trying to run a server on my PC for more than 2 hours but can't get it working

I've downloaded and ran the medieval server shell script and it works

However, when I type in my public IP to the Minecraft client (Medieval MC from GDLauncher) it just won't work

I get a Server timed out error

The thing is, it's not just my friend who can't join the server. I can't connect to the server running on my own PC

[fast lark]

you need to type in localhost

to join your own server

[marsh fjord]

I've enabled port forwarding on my router's admin panel, like so:

[marsh fjord]

That doesn't work either, let me send the error message

Plus, if I connect to my own server over localhost, how is my friend going to connect?

[fast lark]

with your IPV4

you can not connect to your own server using your IP

you need to use localhost to join your own server

[fast lark]

google this error for solutions

you did something incorrectly

https://support.axway.com/kb/177125/language/en this might help

[marsh fjord]

I typed in my IPV4 address and could enter the server, thank you so much for that

However my friend can't connect

[marsh fjord]

The IP address I censored there is the same as the one I used to join the server

So I think requests to port 25565 should redirect to my local IP right?

[marsh fjord]

This is the error he gets:

[fast lark]

probably

[marsh fjord]

so why doesn't it work?

[fast lark]

[marsh fjord]

well

i certainly did something incorrectly, but what is it, that's the question

[rocky talon]

if you can see attempts in the logs

of your friend connecting

that means its an issue on his end likely

[marsh fjord]

Let me check

[rocky talon]

if not

it means its a port forwarding issue

[rocky talon]

btw

the ip address part there

needs your local pc ip

not your public ipv4

idk what u put there

but just as an fyi

[marsh fjord]

I don't see his username or his ip

[rocky talon]

likely a port forward issue then

[marsh fjord]

Yeah I've put this ip from gnome settings

[marsh fjord]

I knew it

Could be because my router firmware is problematic

[rocky talon]

ive no idea if gnome shows a local ip or a public ip

maybe

that sounds entirely possible

[marsh fjord]

Definitely local

[rocky talon]

ah okay

thats strange then, logically the ports should be opened

do you have a firewall setting blocking 25565?

[marsh fjord]

sudo ufw status returns Status: inactive

[rocky talon]

hmm so no firewall either

im assuming hosts are all set normally too

in /etc/hosts

like you have localhost and stuff in there

[marsh fjord]

127.0.0.1 localhost
::1 localhost
127.0.1.1 pop-os.localdomain pop-os

That's all i have in /etc/hosts

[rocky talon]

looks good

how strange

are you confident you gave your friend your public ip?

double check with whatsmyip

or ipchicken.com

[marsh fjord]

Yeah I copied and pasted what https://icanhazip.com shows

But he gets a "Connection timed out: no further information" error

[rocky talon]

since no connection attempts are seen in logs, the connection isnt making it to your pc

can you connect if you use that same public ip

from your own machine

[marsh fjord]

Let me try again

[marsh fjord]

I get this

[rocky talon]

huh

so it must be a port forwarding issue then

if even you cant connect

kinda hard to know what exactly is the issue here tbh

could be the router has some extra setting it needs

[marsh fjord]

Do you think it has anything to do with Port Trigger?

[rocky talon]

shouldnt

port triggering is meant to “port forward” to multiple pcs

its minorly different and isn’t necessary for mc

tho i think it could probably be used

[marsh fjord]

$ netstat -an | grep 25565
tcp6       0      0 :::25565                :::*                    LISTEN     

Is this output normal?

[rocky talon]

do you not have ipv6?

i mean

ipv4

[marsh fjord]

Not in that command's output

In other entries the Local Address column is in the format of [My local IPV4]:[some port]

For 25565, it's just :::25565

[rocky talon]

thats weird

tcp   LISTEN    0      4096                                                      *:25565                                             *:*

ok i cant be bothered to format

but for me

it shows up as this

how did you install the server?

[marsh fjord]

Downloaded this file: https://www.curseforge.com/minecraft/modpacks/medieval-mc-forge/files/4364835

Ran sudo apt install openjdk-18-jdk

Then ran ./start.sh

[rocky talon]

did you change the server.properties by any chance?

[marsh fjord]

Line 48 says server-port=25565 which I think is what matters

[rocky talon]

iirc you dont need to manually set it

but it shouldn't cause issues by being manually set

hmm

i dont know much about networking but it seems something isnt working correctly between your local machine and your router

[marsh fjord]

$ ss -an | grep 25565     
tcp   LISTEN     0      4096                                                                                                      *:25565                              *:*            

When I run it with ss instead of netstat I get the same result

[rocky talon]

oh

[marsh fjord]

Neither do I sadly

[rocky talon]

nevermind what i said then, i have even less idea what’s happening here

do you have another machine at home?

maybe you can try porting it on there

see if its a your pc issue

or router issue

[marsh fjord]

I have a raspberry pi 3b but I'm not sure if it can run it

[rocky talon]

probably not

[marsh fjord]

I also have a somewhat oldish windows pc

[rocky talon]

sounds like it would explode if you tried

maybe try a vanilla server

just for testing

[marsh fjord]

Good idea

Though it's getting late here, so I'll try and post the results tomorrow

[marsh fjord]

The same thing happens, I can join my own server through the local ip but the public ip will throw this error:
