multiplayer : networking

I checked and no, there are no create sessions or destroy (I added only logout just in case one)… so yeah, not working with sessions
I noticed, when I tested for myself, and even I cant login when I put the server online and try to log in

cmd : netstat -n

TCP 127.0.0.1:80 127.0.0.1:7280 FIN_WAIT_2

And yeah, once again, after I close the connection it works again.
