await AuthenticationManager.GetExternalLoginInfoAsync() returning null

Question

When i try to login with an external provider the first time this return null then i press again in the provider and everything is fine. I think is something with cookies because the error happen when i delete all cookies and try again.

If I remove all Session and TempData everything works OK, why is that?

public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
    var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
    if (loginInfo == null)
    {
        Elmah.ErrorSignal.FromCurrentContext().Raise(new NotImplementedException("Error ExternalLoginCallback"));
        TempData["_Error"] = "El incio de sesión con redes sociales no está disponible en este moemento, intente con su usuario y clave";
        return RedirectToAction("Login");
    }
}

    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {

                {
                    /*
