Increase the timeout when logging with external provider

Question

I am using ASP.NET Core 5 Identity with Google as External login.

After I login in Google I get a 500 error when getting back to my application.

The error occurs when accessing the callback url "/signin-google" in my application.

When checking the error details it says it is a 60 seconds timeout error.

How to check of the real error is? I tried to increase the timeout using:

I tried in my application Startup's ConfigureServices method:

  services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddGoogle("Google", x => {
      x.ClientId = clientId;
      x.ClientSecret = clientSecret;
      x.RemoteAuthenticationTimeout = TimeSpan.FromSeconds(240);
    });

But strangely I get the same 60 seconds timeout error.

You need change the time for BackchannelTimeout.
