Gameserver connection lost

Hello Devs. I am currently setting up my L2 server using L2Jserver pack. I host the server from my pc so other people and friends can join and help me while in development state.

Once the server got up, everything worked fine. After 5 or 10 minutes another guy was about to join the server and told me that the server is down, even though there were a few people online at that moment. Long story short, what's happening is that the server runs fine but after a few minutes if somebody tries to login (or just restarts the game) the login console shows that it has lost connection to the gameserver. I have checked hexids, db connection and everything like 10 times but no luck. It is weird because the server never actually closes. It's just that the login loses touch of the gameserver and then shows it as "Down". I really need some help.
