Hi Fellas,

my web service is working fine in my local but when i published it in our server it goes all wrong
it receives error:
"A connection attempt failed because the connected party did not properly respond after a period of time in"

my webservice should receive the code generated by our third party


here's my code:

 Uri uri = new Uri(url, UriKind.Absolute);
WebResponse objResponse;
WebRequest objRequest;
objRequest = System.Net.HttpWebRequest.Create(url);
objRequest.Proxy = System.Net.HttpWebRequest.GetSystemWebProxy();
objRequest.Proxy.Credentials = CredentialCache.DefaultCredentials;
objResponse = objRequest.GetResponse();

any idea on this error?

appreciate your help here!!! :)
