Connection issues with Server

Privat344 · November 19, 2023

Hey,

i have a minecraft Server running remotely on a Ubuntu 22.04-Server, that has some weird connection issues, that I don't understand. Can you help me?

So, If I try to connect to the server from the wifi it is on with a 192.blabla-adress, everything is working fine.

When i ping it from another wifi, the server responds.

When trying to connect to the server via ssh remotely, it doesn't respond and leaves a "timed out" error on my end.

When trying to connect to the Minecraft-Server, that is running on the Server, it can't connect and leaves me this error: Cannot invoke "java.net.InetAdress.getHostAdress()" because the return value of "java.net.InetSocketAdress.getAdress()" is null" and on the server list it says " Can't reach server".

Do you have any idea, how to make everything work again? Everything was working fine, until I swapped the ethernet cable from Port 2 on the Server to Port 1, but I don't think that is the solution to my problem, since it works partially. I currently do not have access to the server physically, only remotely via my Teamviewer-PC, that can ssh onto it (and has access to the router aswell).

Is the other wifi on the same subnet?
