Google OAuth Api not redirecting on Login - google-api

Question

I try to authenticate my user using Google authentication services
When i run this code on local server its working fine (It redirects to google login and after successful login its hit call back on redirectPath).
But when publish this code on Production server then its not working.
When I debug this code, I found its redirect and open the google login page on hosted environment(Where application is published).
here is my code - Please help
string redirecrPath = "http://localhost:1212/Admin/YouTubeIntegration/Success";
UserCredential credential;
using (var stream = new FileStream(Server.MapPath("/XmlFile/client_secrets.json"), FileMode.Open, FileAccess.Read))
{
GoogleAuth.RedirectUri = redirecrPath;
credential = await GoogleAuth.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
new[] { YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeReadonly, YouTubeService.Scope.YoutubeUpload },
"user",
CancellationToken.None,
new FileDataStore(this.GetType().ToString())
);
}
Please let me know if you need more information.
Thanks in Advance

The code to login from a web page is not the same as the code to login with an installed application. Installed applications can spawn the login screen directly on the current machine. If you tried to do that on a webserver it wouldnt work the following is the code for using web login
using System;
using System.Web.Mvc;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Auth.OAuth2.Flows;
using Google.Apis.Auth.OAuth2.Mvc;
using Google.Apis.Drive.v2;
using Google.Apis.Util.Store;
namespace Google.Apis.Sample.MVC4
{
public class AppFlowMetadata : FlowMetadata
{
private static readonly IAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = "PUT_CLIENT_ID_HERE",
ClientSecret = "PUT_CLIENT_SECRET_HERE"
},
Scopes = new[] { DriveService.Scope.Drive },
DataStore = new FileDataStore("Drive.Api.Auth.Store")
});
public override string GetUserId(Controller controller)
{
// In this sample we use the session to store the user identifiers.
// That's not the best practice, because you should have a logic to identify
// a user. You might want to use "OpenID Connect".
// You can read more about the protocol in the following link:
// https://developers.google.com/accounts/docs/OAuth2Login.
var user = controller.Session["user"];
if (user == null)
{
user = Guid.NewGuid();
controller.Session["user"] = user;
}
return user.ToString();
}
public override IAuthorizationCodeFlow Flow
{
get { return flow; }
}
}
}
