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: 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

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

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

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

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

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

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.

Thank you,

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.
