Ok, I've made changes to server, I've tried 2 players and it works perfectly fine,
But, one of my friends who wants to test for me can't connect to my server...
Connected once then this is server log:

Code:

[20:00:39] [connection] X.XX.251.242:37731 requests connection cookie.
[20:00:40] [connection] incoming connection: X.XX.251.242:37731 id: 0
[20:00:41] [join] AmerZompire has joined the server (0:X.XX.251.242)
[20:00:51] [death] AmerZompire died 255
[20:01:56] [part] AmerZompire has left the server (0:0)
[20:02:06] [connection] incoming connection: X.XX.251.242:40483 id: 0
[20:02:06] [connection] incoming connection: X.XX.251.242:44114 id: 1
[20:02:06] [warning] dropping a split packet from client

After that player couldn't join at all, even after server restart, retrieving info problem...
But I could join easily and serverchecker could find my server too...

Is it my server or him?
Why am I getting these warnings?
