WCF http绑定错误：内容类型text / html与绑定的内容类型不匹配（text / xml; charset = utf-8）

Question

我有一个WPF客户端，它使用WCF服务，该服务是在Winforms应用程序中自托管的。客户端通过VPN连接访问服务服务器。首次初始化时，客户端应用程序会从服务中捕获异常：

There was a problem reaching the service. 
The content type of text/html of the response message does not match the content type of the binding (text/xml;charset=utf-8).
If using a custom encoder, be sure that the IsContentTypeSupported method is
implemented properly.

该服务正在运行，没有问题，只有在通过VPN连接时才会出现此问题，而不是从与服务VM位于同一域的Visual Studio开发环境中出现：

此异常仅在首次初始化时发生，当我再次运行客户端应用程序时，问题已解决＆amp;一切都按预期运行。这是我的服务应用程序配置：

  <services>
  <service name="IsesService.IsesService">                           
    <endpoint address="" binding="basicHttpBinding" contract="IsesService.IIsesService" bindingConfiguration="basicHttp">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>     
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://EMEA-DIIS01v:8082"/>
      </baseAddresses>
    </host>
  </service>
</services>

 <behavior>         
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />
      <dataContractSerializer maxItemsInObjectGraph="2147483646" />          
      <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>

 <bindings>
  <basicHttpBinding>
    <binding name="basicHttp"
             useDefaultWebProxy="false"
             maxReceivedMessageSize="2147483647" 
             maxBufferSize="2147483647"
             maxBufferPoolSize="2147483647"
              >
      <readerQuotas maxArrayLength="2147483647"
                maxBytesPerRead="2147483647"
                maxDepth="2147483647"
                maxNameTableCharCount="2147483647"
                maxStringContentLength="2147483647"/>      
    </binding>
  </basicHttpBinding>
</bindings>

客户方：

  <system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IIsesService" useDefaultWebProxy="false"
             maxReceivedMessageSize="2147483647"
             maxBufferSize="2147483647"
             maxBufferPoolSize="2147483647">
              <readerQuotas maxArrayLength="2147483647"
                        maxBytesPerRead="2147483647"
                        maxDepth="2147483647"
                        maxNameTableCharCount="2147483647"
                        maxStringContentLength="2147483647"/>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://emea-diis01v:8082/" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IIsesService" contract="ServiceReference.IIsesService"
            name="BasicHttpBinding_IIsesService" />
    </client>      
</system.serviceModel>

我在这里错过了一些简单的东西吗？

检查fiddler第一个回复的内容是什么。 使用VPN时可能会有所不同。
