System.Net.Sockets.SocketException (0x80004005): A connection attempt failed because the connected party did not properly respond after a period of time

Hi,

I have been battling this for weeks. I want to read xml string from an rss feed. It works fine on localhost and postman, but after i publish and deploy using FTP to the server, i get this error.

Unable to connect to the remote server at System.Net.HttpWebRequest.GetResponse() at dayrunnerapp.Controllers.HomeController.callRss(String url) System.Net.Sockets.SocketException (0x80004005): 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 52.1.31.92:80 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, Exception& exception)

This is the function that reads the feed

[WebMethod, AllowCrossSiteJson]
        private string callRss(string url)
        {
            string html = String.Empty;
            try
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                request.AutomaticDecompression = DecompressionMethods.GZip;
                request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2";
                request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
                request.Headers.Add("Accept-Language", "en-gb,en;q=0.5");
                request.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7");
                WebRequest.DefaultWebProxy.Credentials = CredentialCache.DefaultNetworkCredentials;
                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                using (Stream stream = response.GetResponseStream())
                using (StreamReader reader = new StreamReader(stream))
                {
                    html = reader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                html = ex.Message+"\n"+ex.StackTrace + "\n" + ex.InnerException + "\n" + ex.InnerException.InnerException;
            }

            return html;
        }

this is the feed url 

var url = "http://www.inboundlogistics.com/cms/rss-feed";

here is part of my web.config file

<system.net><defaultProxy useDefaultCredentials="true" /></system.net>

Please what am i missing?
