一位同事能够毫无问题地使用 Apache Axis 创建代理。
不幸的是，我只能访问桌面版 VS 2012 Express。
尝试添加服务引用时出现此错误：
There was an error downloading 'https://app.hostname.com/services/APP?wsdl/$metadata'.
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 123.456.789.123:443
Metadata contains a reference that cannot be resolved: 'https://app.hostname.com/services/APP?wsdl'.
There was no endpoint listening at https://app.hostname.com//services/APP?wsdl that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 123.456.789.123:443
If the service is defined in the current solution, try building the solution and adding the service reference again.
我从另一边的开发人员那里得到了“为我工作”的待遇，不幸的是我不知道要问的正确问题/如何解决这个问题。
