It is a networking issue on your client computer.you might find this (http://social.technet.microsoft.com/Forums/en-US/Forefrontedgegeneral/thread/0136537c-65f5-4d66-8d75-e65dd92a403c/) useful.

tulasiram3975 7-Sep-12 11:47am

sir that is different issue error code 10060.but in my case it is likeSocketException (0x274c)
i have just hosted on clients local iis server..
may i solve the issue through programming sir..

If FullUri is valid and has correct credentials..then I am afraid not..System.Net.Sockets.SocketException suggests error with creation of connection..

tulasiram3975 7-Sep-12 11:56am

fulluri is valid and have correct credentials sir because it is working on my local iis server. i think it is taking long time to respond and finally showing unable to connect remote server

tulasiram3975 7-Sep-12 12:27pm

Solution 1

try this:

C#

public static string GET(string url)
{
    string webresponse = string.Empty;
    try
    {
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
        request.Method = "GET";
        request.AllowAutoRedirect = false;
        request.Credentials = CredentialCache.DefaultCredentials;
        request.Accept = "*/*";
        request.ContentType = "application/x-www-form-urlencoded";
        request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5";
        try
        {
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream dataStream = response.GetResponseStream();
            StreamReader SR = new StreamReader(dataStream, Encoding.UTF8);
            webresponse = SR.ReadToEnd();
            response.Close();
            dataStream.Close();
            SR.Close();

        }
        finally
        {
            request.Abort();
        }

    }
    catch { }
    return webresponse;
}

}

sir i got the same problem after using your code block at this line : HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Error: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 202.xx.xx.xx:80
sir may i change any internet settings in client PC or any other changes required..

Kuthuparakkal 7-Sep-12 12:20pm

it's problem with your client settings.

tulasiram3975 7-Sep-12 12:30pm

ok can i change those settings. right now am connected with client PC
am unable to find where it is blocking my request in client PC
i just uninstalled anti-virus and turned-off firewall and also not woking

[no name] 7-Sep-12 16:14pm

If you can not ping from client's system to 202.xx.xx.xx, then there is no use in looking through the code.

tulasiram3975 8-Sep-12 0:00am

internet is working in client PC ping his ip address it is showing correct (0% loss) but ping our API server address it is not showing..(100% loss) how can i rectify this problem please help me..

Kuthuparakkal 10-Sep-12 2:00am

is it stand alone PC or in a Network ? If on a network so you can ask your network admin to create an exception on firewall to access the API machine.

tulasiram3975 13-Sep-12 0:42am

ok sir... but i did some changes in control panel-->windows firewall -> inbound --> created one rule ..
but it did't worked for me..

Kuthuparakkal 13-Sep-12 1:15am

tulasiram3975 20-Sep-12 5:42am

but from code it is not taking..
i dont know why..??

Kuthuparakkal 20-Sep-12 6:21am

request.Credentials = CredentialCache.DefaultCredentials;

Solution 3

The below line solved my timeout problem while GetResponse()

request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5";

Thanks mate!
