常量「System.ServiceModel.EndpointNotFoundException：在<Service URL>處沒有端點偵聽」錯誤

我有一些WCF服務，在專用服務器上運行IIS。這些服務有他們的客戶。總而言之它的工作原理，但每當我在客戶端級別中查找日誌，我平時看到的這幾樣的錯誤：常量「System.ServiceModel.EndpointNotFoundException：在<Service URL>處沒有端點偵聽」錯誤

System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at <Service URL> that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. 

---> System.Net.WebException: Unable to connect to the remote server 
---> System.Net.Sockets.SocketException: A socket operation was attempted to an unreachable network <Service IP>:80 
    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, Int32 timeout, Exception& exception)

    at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) 
    at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

但就這同一個程序將發送將正常工作後請求。

這是WCF服務的配置：

<netTcpBinding> 
     <binding name="config" closeTimeout="0:5:0" openTimeout="0:5:0" sendTimeout="0:5:0" receiveTimeout="0:5:0" 
       maxBufferPoolSize="8388608" maxBufferSize="8388608" maxReceivedMessageSize="8388608" maxConnections="8388608"> 
      <readerQuotas maxArrayLength="8388608" maxNameTableCharCount="8388608" maxStringContentLength="8388608"/> 
      <security mode="None"/> 
     </binding> 
</netTcpBinding>

和

<basicHttpBinding> 
     <binding name="config2" closeTimeout="0:5:0" openTimeout="0:5:0" sendTimeout="0:5:0" receiveTimeout="0:5:0" 
       maxBufferPoolSize="838860800" maxBufferSize="838860800" maxReceivedMessageSize="838860800"> 
      <readerQuotas maxArrayLength="838860800" maxNameTableCharCount="838860800" maxStringContentLength="838860800"/> 
      <security mode="None"/> 
     </binding> 
</basicHttpBinding>

服務行爲：

<behavior> 
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> 
      <serviceMetadata httpGetEnabled="false"/> 
      <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
      <serviceDebug includeExceptionDetailInFaults="false"/> 
      <dataContractSerializer maxItemsInObjectGraph="838860800"/> 
</behavior>

我認爲有可能是一個極限某處日e同時連接的數量。或者，也許它在IIS設置或WCF服務配置中的東西。但我找不到什麼，在哪裏。

此外，NetTcpBinding配置有一個屬性MaxConnection，但basicHttpBinding沒有。

非常感謝您的幫助！

在web.config的system.serviceModel節中包含'Services'配置。 – 2015-12-07 12:49:07

以下是我自己的Web.config（適合我的項目）的解決版本。有用的提示可以從以下工作樣本中挑選出來。 - Sujayyendhiren

<service name="WelcomeSOAPXMLService"> 
    <endpoint address="http://localhost:16672/Service.svc" binding="basicHttpBinding" contract="IWelcomeSOAPXMLService"/>
