This is because no agent is available to service your request, not even one that would return your request with an error message.
这是因为没有可用的代理可以服务于您的请求，甚至没有一个代理可以用一个错误消息返回您的请求。
The service requesters usually send the request to a service provider, which responds with a solution to the request or an error message if the request cannot be processed.
服务请求程序通常会将请求发送到服务提供程序，服务提供程序会提供请求的解决方案（如果无法对请求进行处理，则为错误消息）来进行响应。
