Yahoo PlaceFinder API Connection Issues - asp.net-mvc-3

Question

I'm trying to used Yahoo's PlaceFinder API to get longitude and latitude for a postcode. Everything works fine on my local machine but when I upload it to my production server I get a connection refused error from Yahoo. I've copied my code below:
Dictionary<string, decimal> GetYahooGeoCode(string postcode)
{
string url = "http://where.yahooapis.com/geocode?flags=J&appid=[My_App_ID]&location=";
decimal latitude = 0;
decimal longitude = 0;
try
{
dynamic yahooResults = new Uri(url + postcode).GetDynamicJsonObject();
foreach (var result in yahooResults.ResultSet.Results)
{
latitude = (decimal)result.latitude;
longitude = (decimal)result.longitude;
}
Dictionary<string, decimal> geoCode = new Dictionary<string, decimal>();
geoCode.Add("latitude", latitude);
geoCode.Add("longitude", longitude);
return geoCode;
}
catch (Exception ex)
{
Log4NetLogger logger = new Log4NetLogger();
logger.Error(ex);
return null;
}
}
The error I'm getting is: No connection could be made because the target machine actively refused it. Does anyone have any ideas on this? I have done a lot of searching and can't seem to find any information on this problem. I don't know if this makes any difference but my production server is a dedicated Cloud server. Any help would be appreciated.

I try to solve your problem here my solition:
Check your web.config:
<system.net>
<defaultProxy />
</system.net>
And my code (GetDynamicJsonObject() not parsed the response):
string postcode = "10003";
string url = String.Format("http://where.yahooapis.com/geocode?state={0}&postal={1}", "NY", postcode);
Dictionary<string, decimal> geoCode = new Dictionary<string, decimal>();
System.Xml.Linq.XDocument xDocument = XDocument.Load(url);
var latlon = (from r in xDocument.Descendants("Result")
select new { latitude = r.Element("latitude").Value, longitude = r.Element("longitude").Value }).FirstOrDefault();
if(null != latlon)
{
geoCode.Add("latitude", Convert.ToDecimal(latlon.latitude));
geoCode.Add("longitude", Convert.ToDecimal(latlon.longitude));
}
