mvc 5 Set Cookie Expire, but expiration back to 01/01/0001 - asp.net-mvc

Question

I set cookie when login success like this :
public JsonResult LoginWithPassword(String password)
{
Response.Cookies.Remove("Auth");
string CookieName = "Auth";
long UserId = 4;
HttpCookie myCookie = HttpContext.Response.Cookies[CookieName] ?? new HttpCookie(CookieName);
myCookie.Values["UserId"] = UserId.ToString();
myCookie.Values["LastVisit"] = DateTime.Now.ToString();
myCookie.Expires = DateTime.Now.AddDays(1);
HttpContext.Response.Cookies.Add(myCookie);
return Json(new { IsSuccess = true, ReturnUrl = returnUrl });
}
else
{
return Json(new { IsSuccess = false, Message = "Login fail, Wrong Password" });
}
}
and i read it in next page/action :
public ActionResult Index()
{
if (HttpContext.Request.Cookies["Auth"] == null)
return RedirectToAction("Login", "Access");
return View();
}
Really strange the cookie of "Auth" always empty. When i check the expiration date in debugging breakpoint, i get expiration date : 01/01/0001.
why this happend and how to solve this?
This action in two differents controller

I have tried to implement your code to create cookie. Same code is working fine in MVC5 at my end in firefox browser.
I have used code as below to create cookie -
Response.Cookies.Remove("Auth");
string CookieName = "Auth";
HttpCookie cookie = HttpContext.Response.Cookies[CookieName] ?? new HttpCookie(CookieName);
//HttpCookie cookie = new HttpCookie("Cookie");
cookie.Value = "Hello Cookie! CreatedOn: " + DateTime.Now.ToShortTimeString();
cookie.Expires = DateTime.Now.AddDays(5);
this.ControllerContext.HttpContext.Response.Cookies.Add(cookie);
In addition the check on "Auth" cookie is successful on Index page as -
public ActionResult Index()
{
if (HttpContext.Request.Cookies["Cookie"] == null)
return RedirectToAction("Login", "Account");
return View();
}
Alternatively I suggest to
1) Set Expiry after cookie is created in login page OR
2) add decimal in expiry days eg. 1.0 or 5.0. See article at link -
