Question

我正在编写第一个连接到基于XML的服务的C＃Web应用程序。它要求我提供证书并提供XML流。它似乎正确验证，但它给出了以下错误：

连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机无法响应10.1.10.4:3128

有趣的是，我不是代理人或类似的东西。我正在直接连接到互联网。有一次，我确实使用了具有内部NAT地址的代理。

所以我的问题是：Visual Studio是否有某种我需要更改的默认代理设置？此IP不再用于任何内容，因此我知道我不需要使用任何代理身份验证代码。

您要了解正在发生的事情的唯一方法是使用Fiddler或Microsoft Network Monitor查看网络流量。
