Default authentication challenge not working in aspnetcore

Using hangfire version: 1.6.17
I have successfully setup hangifire on aspnetcore 2.0
I added authorization by using:

app.UseHangfireDashboard("/jobs", new DashboardOptions
{
Authorization = new[] { new HangfireAuthorizationFilter() }
});

and

public class HangfireAuthorizationFilter :IDashboardAuthorizationFilter
    {
        private const string PERMISSION = "read:jobs";
        public bool Authorize(DashboardContext context)
        {
            var httpContext = context.GetHttpContext();
            // allow only users with correct permission
            if (httpContext.User.Identity.IsAuthenticated)
            {
                var permissions = httpContext.User.Claims.FirstOrDefault(x => x.Type.Equals(CustomClaims.Permissions))?.Value?.Split(' ');
                return permissions?.Contains(PERMISSION) ?? false;
            }
            return false;
        }
    }

The only problem i cannot resolve is that a blank screen with 401 is returned to the user instead of the default challenge /account/login.

If you access my controllers with the [Authorize] attribute, they are automatically redirected to /account/login, so the loginpath is working.

Even if i specify it specifically, the user is not redirected while accessing Hangfire unauthorised:

services.AddAuthentication(options =>
    {
     options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
     options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
     options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    })
     .AddCookie(options =>
     {
       options.LoginPath = "/Account/Login/";
     })

Somebody an idea?
