C# Connection error

[EDN Admin]

I am creating a program which connects to a gaming provider called Steam. It is supposed to connect and then turn a account online. For some reason it works sometimes and sometimes I get this error. I am on a mac, using monodevelop, and have the latest mono beta build. Please help!
