IdentityServer4 Asp.Net Core Identity

I'm trying to create basic IdentityServer4 with Asp.Net Core Identity, as in this tutorial.

But when I call the login method:

return Challenge(new AuthenticationProperties {
RedirectUri = "/Home/Index"
}, "oidc");

return Challenge(new AuthenticationProperties {
RedirectUri = "/Home/Index"
}, "oidc");

I get a 404 error:

Do I need any additional Views and Controllers? I thought that what is in Asp.Net Core Identity will be used.

My IdentityServer4 config:

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>()
.AddDefaultUI()
.AddEntityFrameworkStores<ApplicationDbContext>();

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

// configure identity server with in-memory stores, keys, clients and scopes
services.AddIdentityServer()
.AddSigningCredential("CN=tst")
.AddInMemoryPersistedGrants()
.AddInMemoryIdentityResources(Config.GetIdentityResources())
.AddInMemoryApiResources(Config.GetApiResources())
.AddInMemoryClients(Config.GetClients())
.AddAspNetIdentity<IdentityUser>();
}


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}

//app.UseHttpsRedirection();
//app.UseCookiePolicy();


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


My Client Config:

public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication("oidc")
.AddCookie("Cookies")
.AddOpenIdConnect("oidc", optins =>
{
optins.SignInScheme = "Cookies";
optins.Authority = "http://localhost:5000";
optins.RequireHttpsMetadata = false;

optins.ClientId = "mvc";
optins.ClientSecret = "secret";
optins.ResponseType = "code id_token";
optins.GetClaimsFromUserInfoEndpoint = true;

optins.Scope.Add("openid");
optins.Scope.Add("profile");
//optins.Scope.Add("email");
optins.Scope.Add("api1");

optins.ClaimActions.Add(new JsonKeyClaimAction("role", "role", "role"));
optins.SaveTokens = true;

});

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


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}

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

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


There are no errors in the IdentityServer4 console.
