我们为我们的应用程序开发了几个 WCF 服务。从我们的 Web 应用程序中，我们能够通过单个服务器到达这些端点。当我们尝试通过负载均衡器访问它们时，我们收到以下错误：

There was no endpoint listening at net.tcp://<IP>:443/<Service API> that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

Server stack trace:

   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

附加信息：

  • 作为 Windows 服务托管的 WCF 服务
  • 443 端口上的 WCF 服务列表
  • TCP是Web和服务之间的通信协议

如果我可以提供任何其他信息，请告诉我。

任何帮助将不胜感激。

我有同样的问题。我设法通过将其添加到服务器端的配置文件来解决它：

  <system.net>
<connectionManagement>
  <add address="*" maxconnection="500" />
</connectionManagement>

默认值为 2。有关更多信息，您可以阅读以下内容：扩展 WCF 服务
