My Windows Phone app Get empty response (404 Not Found) Scond time, work's great first time;And always work fine if without SSL

Question

I am building my first windowsPhone 8.1 application ,the role of my application is to create connection with server to get information from it, so I am writing the code to do this process by sending json-rpc request to server to get some information ,I am successful to get it in first time but when I send the second request I am receiving an empty response with 404 error (page not found). But when I call the service without https (http only) it works fine regardless how many time I call it ! ``` public async Task<string> GetDataFromServer(string urlToCall, string JSONData,string RR) { string UserName = “XXXXXXX” string Password = "XXX"; using ( var handler = new HttpClientHandler()) { handler.Credentials = new NetworkCredential(UserName, Password); HttpClient client = new HttpClient(handler); HttpResponseMessage response = null; try { response = await client.PostAsync(urlToCall, new StringContent(JSONData.ToString(), Encoding.UTF8, " application/json")); string res = response.Content.…

        string Password = "XXXXXXXXX";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(urlToCall);
        httpWebRequest.Credentials = new NetworkCredential(UserName, Password);
        httpWebRequest.ContentType = "text/json";
        httpWebRequest.Method = "POST";
        using (var streamWriter = new StreamWriter(await httpWebRequest.GetRequestStreamAsync()))
        {
            string json = JSONData;
            streamWriter.Write(json);
            streamWriter.Flush();
        }
        var httpResponse = (HttpWebResponse)await httpWebRequest.GetResponseAsync();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

}
