This is because no agent is available to service your request, not even one that would return your request with an error message.
這是因爲沒有可用的代理可以服務於您的請求，甚至沒有一個代理可以用一個錯誤消息返廻您的請求。
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.
服務請求程序通常會將請求發送到服務提供程序，服務提供程序會提供請求的解決方案（如果無法對請求進行処理，則爲錯誤消息）來進行響應。
