Windows WCF client with internet proxy server showing error The server committed a protocol violatio

Our team trying to create a windows application(c#) to call a WCF service using internet proxy server

Showing exception “The server committed a protocol violation. Section=ResponseStatusLine” while calling WCF service

Please give suggestion to solve this problem/any alternative solution

 

//Code for creating proxy
publicstaticDevicesServiceClientCreateProxy()
{
 
var proxy =newDevicesServiceClient("BasicHttpBinding_IDevicesService");

 
BasicHttpBinding binding =newBasicHttpBinding();
  binding
.Security.Mode=BasicHttpSecurityMode.None;
  binding
.Security.Transport.ProxyCredentialType=HttpProxyCredentialType.None;
  binding
.UseDefaultWebProxy=false;
  binding
.ProxyAddress=newUri(string.Format("http://{0}:{1}","192.168.0.20","808"));
  proxy
.Endpoint.Binding= binding;

  proxy
.ClientCredentials.UserName.UserName="Username";
  proxy
.ClientCredentials.UserName.Password="Password";
}
