Those type of routers never Port Forward BL
That's a lie. I have the same router. I can host just fine.
Did you set the static IP?
Did you forward ports 28000-28030?
Is your server port set to 28000?
Did you check the status of the server yourself?
If yes, did you leave the game to do so? That would mean you closed the server, so then it turns out dead.
Did you make sure to host Internet and not LAN?
Did you remove the game password?
Did you set the player count higher than 1?
