I followed the simple steps but all I get is “this page is not working” 401.

```auto
public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            // 1. Add Authentication Services
            services.AddAuthentication(options =>
            {
                options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;

            }).AddJwtBearer(options =>
            {
                options.Authority = "https://amtech.auth0.com/";
                options.Audience = "https://api.alerts.com";
            });

            services.AddAuthorization(options =>
            {
                options.AddPolicy("read:messages", policy => policy.Requirements.Add(new HasScopeRequirement("read:messages", "amtech.auth0.com")));
            });

            // register the scope authorization handler
            services.AddSingleton<IAuthorizationHandler, HasScopeHandler>();

            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            // 2. Enable authentication middleware
            app.UseAuthentication();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }

  // GET: api/<controller>
        [HttpGet]
        [Authorize]
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

```

Not sure what I’m doing wrong. gotta be something simple. .netcore 2.1

Thanks,

Aaron
