GetExternalLoginInfoAsync() return null for facebook only

[Pom-Veerawat]

Previously, I facing the same problem, I upgraded to version 3.0.1 and it is working. Now I have the same problem again and try to upgrade with nuget to version 4.2.2 but this time it is not working. I got error=accesse_denied in url, and return null in GetExternalLoginInfoAsync(). google is working, just only facebook return null

        Startup.Auth.cs
         var facebookOptions = new Microsoft.Owin.Security.Facebook.FacebookAuthenticationOptions()
        {
            AppId = "xx",
            AppSecret = "xx",
            CookieManager = new Microsoft.Owin.Host.SystemWeb.SystemWebCookieManager()
        };

        app.UseFacebookAuthentication(facebookOptions);

        AccountController.cs
         public ActionResult ExternalLogin(string provider, string returnUrl)
          {

              ControllerContext.HttpContext.Session.RemoveAll(); //this is for swap facebook and google

              // Request a redirect to the external login provider
              return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl }));
          }

           [AllowAnonymous]
          public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
          {
              if(returnUrl == null)
              {
                  returnUrl = "";
              }               

              var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
              if (loginInfo == null) // this always return null
              {
              .
              .
              }
         }

error=accesse_denied sounds like it came from facebook's site, double check your appid and secret. Also, did you get any errors in the browser from facebook?

no just only error=accesse_denied. I have double check both appid and secret. It is correct.

*edit attach link /Account/ExternalLoginCallback?error=accessdenied#=_

*request url to facebook before login

user_denied implies the user is declining to log in, or is declining some of the permissions you've requested.
