连接尝试失败，因为一段时间后连接方未正确响应或连接的主机未能响应 [英] A connection attempt failed because the connected party did not properly respond after a period of time or connected host has failed to respond

问题描述

我正在开发Windows服务，该服务从特定的URL下载图像.该服务可以在我的计算机上正常运行，但是当我在服务器上安装该服务时，它不会下载该映像，并且会出现以下错误:

I'm developing a windows service, that downloads images from a specific URL. The service runs correctly on my computer but when I install it in the server it does not download the image and it gives the following error:

System.Net.WebException:无法连接到远程服务器---> System.Net.Sockets.SocketException:连接尝试失败，因为一段时间后连接方未正确响应，或者建立连接失败，因为连接的主机未能响应212.100.220.117:80

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: 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 212.100.220.117:80

在System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot，SocketAddress socketAddress)

at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)

在System.Net.ServicePoint.ConnectSocketInternal(布尔型connectFailure，Socket s4，Socket s6，Socket&套接字，IPAddress&地址，ConnectSocketState状态，IAsyncResult asyncResult，Int32超时，Exception&异常)

at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception)

-内部异常堆栈跟踪的结尾---

--- End of inner exception stack trace ---

System.Net.WebClient.DownloadDataInternal上的

(URI地址，WebRequest& request) 在System.Net.WebClient.DownloadData(Uri地址) 在System.Net.WebClient.DownloadData(字符串地址)

at System.Net.WebClient.DownloadDataInternal(Uri address, WebRequest& request) at System.Net.WebClient.DownloadData(Uri address) at System.Net.WebClient.DownloadData(String address)

可能是什么原因导致该错误，我该如何解决? 我阅读了此页面: http://support.microsoft.com/kb/318140

What might be causing the error and how can I resolve it? I read this page: http://support.microsoft.com/kb/318140

但是我不确定这是否是问题，是否应该在配置中编写哪个代理.询问您的建议.

but I'm not sure if this is the problem, and if it is what proxy should I write in the config. Asking you for your advice.

谢谢

推荐答案

我找到了答案.我试图从服务器访问公用地址" http://mywebsite.com/images/" .取而代之的是，我使用托管网站的服务器的本地IP来运行它.

I found the answer. I was trying to access the public address "http://mywebsite.com/images/" from the server. Instead of that I used the local IP of the server hosted the website and it's now working.
