Google authentication not working when deployed to azure

I am authenticating using Google. The below code works fine when I run it locally whereas it throws an error when I deploy it to azure:

 HttpWebRequest webRequest = 
(HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");
                    webRequest.Method = "POST";
                    Parameters = "code=" + code + "&client_id=" + googleplus_client_id + "&client_secret=" + googleplus_client_secret + "&redirect_uri=" + googleplus_redirect_url + "&grant_type=authorization_code";
                    byte[] byteArray = Encoding.UTF8.GetBytes(Parameters);
                    webRequest.ContentType = "application/x-www-form-urlencoded";
                    webRequest.ContentLength = byteArray.Length;
                    Stream postStream = webRequest.GetRequestStream();
                    postStream.Write(byteArray, 0, byteArray.Length);
                    postStream.Close();
                    WebResponse response = webRequest.GetResponse();//**Error Occurs here**

I also tried

var values = new NameValueCollection();
var resp = client.UploadValues("https://accounts.google.com/o/oauth2/token?" + Parameters, values );
var responseString = Encoding.Default.GetString(resp);
serStatus = JsonConvert.DeserializeObject<GooglePlusAccessToken>(responseString);

And again this worked locally, but when I deployed it to azure it didn't work

The redirect url is like below:

https://sample.com/Home/User?code=4/uQB37PKUFlID8dSLFFTsYLEDdHWWOprWaMtpa6YasdxxxxxxxxxxH8OQVxg3UZMoDc&scope=email%20profile%20https://www.googleapis.com/auth/userinfo.profile%20https://www.googleapis.com/auth/userinfo.email

I get the below error message and stack trace enter image description here

It might be related to the redirect URL not being in the approved list at the Google side, whereas the localhost used when you run locally is.

Take a look at OAuth 2.0 >> Web applications (ASP.NET MVC) for more information.

Hope it helps!
