    Are you checking for an error message sent by the external login provider?
    Here is how I am doing it using an ExternalLoginCallback action in my account controller:

    [AllowAnonymous]
public async Task<IActionResult> ExternalLoginCallback(string remoteError = null)
{
    if (remoteError != null)
    {
        ModelState.AddModelError(string.Empty, $"Error from external provider: {remoteError}");
        return View("Login", loginUser);
    }
    var loginInfo = await _signInManager.GetExternalLoginInfoAsync();
    
    (rest of code...)
}
