No connection could be made because the target machine actively refused it 127.0.0.1

Question

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 ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:14012 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) at System.Net.HttpWebRequest.GetRequestStream() at Limoallover.InsertSoapEnvelopeIntoWebRequestUS(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest) at Limoallover.dawUpdateDriverStatus(String apiId, String apiKey, String idTrip, String tripCode, String statusCode) at Limoallover.UpdateJobStatus(String Lat, String Lng, Int32 DriverID, Int32 nJobStatus, Int32 nJobId, String CompanyID, String idTrip, String tripCode, String statusCode)

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

<system.net>
  <defaultProxy> 
    <proxy usesystemdefault="False"/> 
  </defaultProxy>
</system.net>

The exception message says you're trying to connect to the same host (127.0.0.1), while you're stating that your server is running on a different host. Besides the obvious bugs like having "localhost" in the url, or maybe some you might want to check your DNS settings.
