C# 不重定向到未授权的自定义错误页

我正在尝试设置自定义错误页面，到目前为止，我有一个404未找到的错误页面，它工作得很好，但我正在尝试为401 Unauthorized设置一个自定义错误页面，例如：如果您尝试输入需要某种管理员登录的URL，它应该显示401 Unauthorized错误。无论我遇到什么错误，它都会将我重定向到404 Not Found，尽管它应该显示401 Unauthorized错误

这是我犯的错误

到目前为止，我一直在使用ActionFilterAttribute&IAuthorizationFilter，它显示默认浏览器错误，但我希望它显示我的自定义错误页面（.cshtml）

误差控制器

[HandleError]
    public class ErrorController : Controller
    {
        public ActionResult Error()
        {
            return View();
        }
        public ActionResult NotFound()
        {
            return View();
        }
        public ActionResult NonSecure()
        {
            return View();
        }
    }

用户控制器。所有UserAuthenticationFilter标记都是不可访问的页面，除非您被授权为用户

public class UserController : Controller
    {
        [UserAuthenticationFilter]

        public ActionResult Management()

            {
                return View(db.Users.ToList());
            }
        }
        [UserAuthenticationFilter]
        public ActionResult Register()
        {
            return View();

                var usr = db.Users.FirstOrDefault(u => u.Email == user.Email && u.Password == user.Password);

                    return RedirectToAction("LoggedIn");
                }
                else
                {
                    ModelState.AddModelError("", "Email or Password is incorrect!");
                }
                return View();
            }
        }

            {
                return RedirectToAction("Management");
            }
            else
            {
                return RedirectToAction("Login");
            }
        }
        [ValidateAntiForgeryToken]
        [Authorize]
        [HttpPost]
