ASP.NET (C#) Question

No connection could be made because the target machine actively refused it

I try to connect to a web service hosted on a different server using the WebRequest Class. The web service returns a string as a Response. While doing so I get an Error:

"System.Net.Sockets.SocketException: No connection could be made
because the target machine actively refused it"

System.Net.WebException: Unable to connect to the remote server --->

After six days I find the answer which make me crazy! The answer is disable proxy at web.config file:

    <proxy usesystemdefault="False"/>
