Hello,
I started a l4d2 server recently and was running fine for first 2 days. Now i come to find out it shows offline/dead on Game Tracker when the server actually is alive with players playing on it. I tried restarting it and it will come online for while then go offline again. any ideas on how to fix this?

My server:----> http://www.gametracker.com/server_info/64.94.238.165:27015/

Anyone? The server doesnt crash if you think this might be the issue. Also i have a program that at crash it starts the server instantly. For example now the server is running on my box ( i checked) i played a few rounds and Gtracker takes more than 20 mins to scan and when it does it shows the server offline. Again after restart the server comes online for small amount of time and then boom dead/offline according to game tracker.

Any admin looking into this?! It seems as when there is no players on the server and server goes to hibernate it can not be scanned. What could be the reason?

Be patient till some admin look at your problem.
