I don't know. Unfortunately, I can't debug it either as I've lost some vital code which I will need to rewrite at some point.

I mean, I can connect with my client on the server using my local ip but I can't host on my ip adress and I can't connect with it."
Assuming you're connected to the internet via a router:
1. Host using 0.0.0.0. If this doesn't work, use your computer's LAN address. You can find this address by opening command prompt and typing
ipconfig.
2. In order to let other people connect to you from the internet, you need to set up
port forwarding on your router. The protocol is TCP, and the port is 3999 by default. Note that if you are hosting behind a router, you can
not connect to yourself using your internet IP, since your computer doesn't know what this IP is (only the router does).

I do indeed have my PC now, although I'm recovering from a brief illness at the moment so I'm trying not to spend too long on the PC. I'll see about doing them in a few days time.
