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

Question

Sometimes I get the following error while I was doing HttpWebRequest to a WebService. I copied my code below too.

System.Net.WebException: Unable to connect         


        

Answer 1

I faced same error because when your Server and Client run on same machine the Client need server local ip address not Public ip address to communicate with server you need Public ip address only in case when Server and Client run on separate machine so use Local ip address in client program to connect with server Local ip address can be found using this method.

 public static string Getlocalip()
    {
        try
        {
            IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());
            return localIPs[7].ToString();
        }
        catch (Exception)
        {

            return "null";
        }

    }
