Hello, thanks for replying,
nobody else has...
I just wanted to quickly reply but I must say I just read your reply and did not do anything with your information yet.
I do have something to say regarding stable connection and static ip connection things you mentioned.
I just played halo pc 16/16 on a server I host aswel (played for a few hours) so im pretty sure it is not that.
Also I am able to host TeamSpeak 3 while playing either KAM and/or Halo so the internet should be good.
Also, the problem usually occurs when the last players leaves the server. Can alsways play several hours on the KAM server with friends without problems. But as soon as the last person leaves it get the error.
I have a modem and router in one.
I have added todays log it might help you help me 
 
PS: you can call me Noob (im used to it)
Again, thanks for replying
