雙工wcf服務不與生產服務器連接，但與本地主機一起運行

Question

我在開發機器上構建了WCF雙工服務。我構建了這個服務，創建了一個測試客戶端，測試了一切，並且它工作正常。然後我大膽地將它移到我的生產服務器上。現在我已經轉移到生產服務器，我不能使用雙工服務。塊了一段時間，並給超時錯誤

客戶端代碼：

 static void Main(string[] args) 
     { 
      EndpointAddress endPointAddress = new EndpointAddress("http://ProductionServer:8088/sampleWCF/Service1.svc"); 
      try 
      {     
       InstanceContext instanceContext = new InstanceContext(new CallbackHandler()); 
       ServiceDuplexClient client = new 
        ServiceDuplexClient(instanceContext, new WSDualHttpBinding(), endPointAddress); 

       client.ClientCredentials.UserName.UserName = "bipin"; 
       client.ClientCredentials.UserName.Password = "pass@123"; 

       client.Open(); 

       client.GetDataFromXml(); 
      } 
      catch (Exception ex) 
      { 
       Console.WriteLine(string.Format("Error connecting to service. {0}", ex.Message)); 
      } 
      Console.ReadLine(); 
     } 

我得到錯誤時開放代理：即client.Open（）;

客戶端無法在配置的超時（00:00:00）內完成安全協商。目前的談判階段是1（00:00:00）。來源= mscorlib

請幫我解決這個錯誤。任何幫助將是可觀的。謝謝。

Answer 1

我的建議是不要使用WSDualHttpBinding的雙工 - 它使用的整個模型是很容易失敗，並且不通過任何強勁配置的防火牆

開關雙工工作NetTcpBinding的。客戶端創建到服務器的出站連接，然後使用相同的連接傳遞雙工消息（WSDualHttpBinding嘗試建立從服務器到客戶端的另一個連接，這幾乎肯定會在生產網絡中被阻塞
