我有一个针对WCF（.net v4）的通用托管服务。它允许以插件样式删除多个代理，每个代理都有自己的配置文件。它被编写为服务，因为所有站点都没有安装IIS或WAS，但我们可以指定.net v4和我们的客户服务。
我们对HTTP，HTTPS或TCP（没有凭据）没有任何问题。当我们添加证书到服务器时，它似乎没有问题。一旦我们试图调用服务器，我们就会出现通道故障。我们编写了一个小型自托管程序，它使用配置文件而不是以编程方式创建endpoing，并且它没有任何问题。我们只能推测我们错过了一个设置，但无法确定哪个。
我们得到的错误如下所示。看来由于某种原因客户端尝试建立我们未在主机中配置的双通道tcp连接。
