Odd error

I'm not sure if its just my computer or what. But I'm trying to access the server through a different computer thats on the same internet (meaning that both machines have the same ip address) However for some reason on my laptop I cannot connect to the server I get the checking for server error after clicking start game....Any idea of what could be causing this. All of my other players can access the server fine.

I'll owe you dinner if anyone can help me with this! :)

Try a game.exe with 127.0.0.1

As long as you're in the same network as the server use the local.

Thats not working either unfortunately :/. I don't know what exactly is causing this... On the server pc I can use the game.exe with my ip and log in perfectly fine...
