IdentityServer No authentication handlers are registered

Question

i'm using using identityserver token to validate and getting error "No authentication handlers are registered. Did you forget to call AddAuthentication().AddSomeAuthHandler?"

Below is my code

Web API startup.cs:

public void ConfigureServices(IServiceCollection services) {

        var config = Configuration.GetSection("AuthSettings").Get<AuthSettings>();
        services.AddAuthentication(
            options =>
        {
            options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;

        }
        ).AddJwtBearer(o =>
        {
            o.Authority = config.AuthUrl;
            o.Audience = config.AuthAudience; 
            o.RequireHttpsMetadata = false;
            o.SaveToken = true;
            //o.TokenValidationParameters = tokenValidationParameters;
            //o.Configuration = new OpenIdConnectConfiguration();  
            o.BackchannelHttpHandler = new HttpClientHandler()
            {
                ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator,
                Proxy = new WebProxy(Configuration["System:Proxy"])
            };
        });
        //services.AddAuthorization(options =>
        //{
        //    options.AddPolicy("PublicSecure", policy => policy.RequireClaim("client_id", config.ClientId));
        //});
        services.AddAuthorization();

Client Side startup.cs:

var authConfig = Configuration.GetSection("AppSettings").Get();

        // Adds an instance of the class that contains credentials
        services.AddSingleton(new ClientCredentialsTokenRequest
        {
            Address = authConfig.AuthURL,
            ClientId = authConfig.AuthClientId,
            ClientSecret = authConfig.AuthClientSecret,
            Scope = authConfig.AuthScope
        });

        services.AddAuthentication();

Please help me to fix my code error Thanks

You need to add the following two lines in your Startup.Configure method:

app.UseAuthentication();
app.UseAuthorization();

Do add them after the useRouting() statement.
