When i use Dedigui2 or Dedicated server for S2 if i click that i want it to show up in the master server list, i will click run or start and then it will say in red letters in that server box "could not connect to master server"
now if i try and run a lan game through that computer it works just fine. (By the way, i have two computers on the same network) and if i start one in the game for internet it wont show up on the other computer.

Help please, thank you

Is that server computer connected to the internet and how is it connected to the internet? You need to forward ports on your router so other people can connect over the internet to your game. www.portforward.com
