How to not make login or register mandatory in asp.net core 2.1?

I added to my project that only logged in users where able to view my website. But now I want to make it so the user doesn't need to be logged in. I already removed thing that I added to my Startup class, and now it gives me an error saying "localhost:5000/Account/Login not found". Here is my startup class:

     public class Startup
{
    IConfiguration configuration;
    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)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });

        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));

        services.AddDefaultIdentity<IdentityUser>()
        .AddEntityFrameworkStores<ApplicationDbContext>();
        //.AddRoles<IdentityRole>()

        services.AddControllersWithViews().AddNewtonsoftJson(options =>
            options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
        );
        services.AddSignalR();

        //services.AddControllersWithViews();
        //services.AddRazorPages();


        //services.AddControllers(config =>
        //{
        //    // using Microsoft.AspNetCore.Mvc.Authorization;
        //    // using Microsoft.AspNetCore.Authorization;
        //    var policy = new AuthorizationPolicyBuilder()
        //                     .RequireAuthenticatedUser()
        //                     .Build();
        //    config.Filters.Add(new AuthorizeFilter(policy));
        //});



        //premite o acesso ao controller IgnicoesAPIController através dos outros controllers
        services.AddTransient<IgnicoesAPIController, IgnicoesAPIController>();
        services.AddTransient<OcorrenciasAPIController, OcorrenciasAPIController>();
        services.AddSingleton<IConfiguration>(Configuration);
    }

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

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

        app.UseAuthentication();

        //SIGNAL R

        //String caminho = configuration["AppSettings:Servidor"] + "/myHub";
        String caminho = Configuration["AppSettings:Servidor"] + "/myHub";

        //endpoints.MapHub<MyHub>(caminho);
        //app.UseSignalR(route =>
        //{
        //    route.MapHub<MyHub>(caminho);

        //});

        app.UseRouting();
       // app.UseAuthorization();
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapHub<MyHub>("/myHub");
            endpoints.MapControllerRoute(
                name: "default",
               pattern: "{controller=Home}/{action=Index}/{id?}");
            //endpoints.MapRazorPages();
        });

       

    }
}

Am I missing something?
