EndpointNotFoundException的可能原因是什么?

我试图找到下面的EndpointNotFoundException异常的潜在原因(在客户端发生,异常是间歇性的)。异常消息描述了两个可能的原因:

  • 没有端点监听。
  • 不正确的SOAP操作。

我验证了两者,端点可用以及SOAP操作。网络配置似乎是正确的,并且所有计算机都已启动,运行且负载非常轻。我还检查了诸如代理(没有),并发(maxConcurrentConnection增加)和性能计数器(一切看起来都正常)之类的东西。这可能是由于客户端库中的错误(我们正在汇集代理)导致我们最终遇到故障状态的代理或某个套接字从未关闭?

简而言之,我想知道在客户端代理中间歇性地导致该异常的原因。

我有完全相同的问题。就我而言,用IP替换计算机名称是可行的。我知道这没有多大意义。

不起作用:

ProcessHandle

可行吗?

<endpoint address="http://MyComputerName:82/MyApplication/MyPath/MyWebService.asmx"

我应该补充一点,浏览器可以使用计算机名完美访问端点。但是,当应用程序进行调用时,它根本不起作用。
