System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send

[ripu shah]

 I have used to get latitude & longitude  by using google Geo-coding API  but while send a request i got this error can you help me to how resolve this issue?

code : 

   string fullAddress = string.Empty;

        if (!string.IsNullOrEmpty(address) || zipCode != null)

        {

            fullAddress = string.Format("{0} {1}", address.Trim().Replace(' ', '+'), zipCode);

        }

        string url = "https://maps.googleapis.com/maps/api/geocode/json?address={0}&sensor=true&key={1}";         //Map.GetMapGeoLocationV2(fullAddress);

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        request.KeepAlive = false;

        request.ProtocolVersion = HttpVersion.Version10;

        request.Credentials = System.Net.CredentialCache.DefaultCredentials;

        request.UseDefaultCredentials = true;

        request.ConnectionGroupName = Guid.NewGuid().ToString();

       // ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

    

        request.Method = "GET";

       

        // var response = request.GetResponse();

        try

        {

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            System.Threading.Thread.Sleep(1000);

            using (var stream = response.GetResponseStream())

            {

                using (var reader = new StreamReader(stream))

                {

                    var result = Newtonsoft.Json.Linq.JObject.Parse(reader.ReadToEnd());

                    outstatus = result.SelectToken("status").ToString() != null ? result.SelectToken("status").ToString() : string.Empty;

                    if (outstatus == "OK")

                    {

                        latitude = result.SelectToken("results[0].geometry.location.lat").ToString() != null ? result.SelectToken("results[0].geometry.location.lat").ToString() : string.Empty;

                        longitude = result.SelectToken("results[0].geometry.location.lng").ToString() != null ? result.SelectToken("results[0].geometry.location.lng").ToString() : string.Empty;

                        var addresscomponentsCount = result.SelectToken("results[0].address_components").Count();

                        for (int i = 0; i < addresscomponentsCount; i++)

                        {

                            var addresscomponentsTypesCount = result.SelectToken("results[0]." + string.Format("address_components[" + "{0}" + "]", i) + ".types").Count();

                            for (int j = 0; j < addresscomponentsTypesCount; j++)

                            {

                                var type = result.SelectToken("results[0]." + string.Format("address_components[" + "{0}" + "]", i) + string.Format(".types[" + "{0}" + "]", j)).ToString();

                                if (type == "administrative_area_level_1")

                                {

                                    state = result.SelectToken("results[0]." + string.Format("address_components[" + "{0}" + "]", i) + ".short_name").ToString();

                                }

                                if (type == "postal_code")

                                {

                                    outZipCode = result.SelectToken("results[0]." + string.Format("address_components[" + "{0}" + "]", i) + ".short_name").ToString();

                                }

                            }

                        }

                        response.Close();

                    }

                    reader.Close();

                }

                stream.Close();

                

            }

        }
