Azure portal. Mvc. Redirect to custom error page doesn't work for 403 error

I have configured owin role-based authorization in my MVC application. Then, I need to add a custom handling of 403 http error

I know two approaches to do it:

1. Web.config settings:

   <customErrors mode="Off" defaultRedirect="~/Error/" redirectMode="ResponseRedirect">
    <error statusCode="403" redirect="~/Error/NoAccess" />
   </customErrors>
   

2. Configuration inside of overridden HandleUnauthorizedRequest method in Authorize attribute:

   if (filterContext.HttpContext.User?.Identity.IsAuthenticated ?? false)
   {
      filterContext.Result = new RedirectToRouteResult(
      new RouteValueDictionary
      {
        {"action", "NoAccess"},
        {"controller", "Error"}
      });
      //I've tried two variants of below: with below line as well as without it 
      filterContext.Result.ExecuteResult(filterContext.Controller.ControllerContext);
   }
   

Both of these methods work well in my local machine when I try to get access to resources which is not allowed for my user and I see my custom page for 403 error, but when I deploy my application on azure portal, I see only white page with the following text : 'You do not have permission to view this directory or page.'. As I may understand, I need to configure this behavior on azure portal as well as I configured it in my code.

Could someone advise with it?

I've found the answer. The problem is appeared in case if I set response code in controller method manually as shown below:

public ActionResult NoAccess()
{
    Response.StatusCode = 403;
    return View();
}

In case if I delete this status setup, redirection works fine. The solution is to set to true the following flag : TrySkipIisCustomErrors

 public ActionResult NoAccess()
 {
     Response.TrySkipIisCustomErrors = true;
     Response.StatusCode = 403;

     return View();
 }

Then everything works correctly as well.
