IdentityServer4 ASP.NET Core Identity does not redirect back to client

Question

I have basic IdentityServer4 with Asp.Net Core Identity. After redirecting to the login page and signing in, IdentityServer does not redirect me back to the client.

IdentiyServer Config:

 new Client
            {
                ClientId = "mvc",
                ClientName = "MVC Client",
                AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,

                ClientSecrets =
                {
                    new Secret("secret".Sha256())
                },

                RedirectUris = { "http://localhost:50309/signin-oidc" },
                PostLogoutRedirectUris = { "http://localhost:50309/signout-callback-oidc" },

                AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    "api1"
                },
                AllowOfflineAccess = true
            }

IdentityServer Startup:

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>()
            .AddDefaultTokenProviders()
            .AddDefaultUI();

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

        services.Configure<IISOptions>(iis =>
        {
            iis.AuthenticationDisplayName = "Windows";
            iis.AutomaticAuthentication = false;
        });

        var builder = services.AddIdentityServer(options =>
        {
            options.Events.RaiseErrorEvents = true;
            options.Events.RaiseInformationEvents = true;
            options.Events.RaiseFailureEvents = true;
            options.Events.RaiseSuccessEvents = true;
            options.UserInteraction.LoginUrl = "/Identity/Account/Login";
            options.UserInteraction.LogoutUrl = "/Identity/Account/Logout";
        })
            .AddSigningCredential("CN=tst")
            .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.UseStaticFiles();
        app.UseIdentityServer();
        app.UseCookiePolicy();
        //app.UseAuthentication();

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

MVC Client Startup:

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

        //JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

        services.AddAuthentication(options =>
        {
            options.DefaultScheme = "Cookies";
            options.DefaultChallengeScheme = "oidc";
        })
            .AddCookie("Cookies")
            .AddOpenIdConnect("oidc", options =>
            {
                options.SignInScheme = "Cookies";

                options.Authority = "http://localhost:5000";
                options.RequireHttpsMetadata = false;

                options.ClientId = "mvc";
                options.ClientSecret = "secret";
                options.ResponseType = "code id_token";

                options.SaveTokens = true;
                options.GetClaimsFromUserInfoEndpoint = true;

                options.Scope.Add("api1");
                options.Scope.Add("offline_access");
            });
    }

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

        app.UseHttpsRedirection();

        app.UseAuthentication();

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

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

There is a warning in the console, but all the URLs are correct Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3] Failed to determine the https port for redirect.

Any ideas what am I doing wrong?

Answer 1

From your code, please change the http to https identityserver works on https only RedirectUris = { "http://localhost:50309/signin-oidc" },

PostLogoutRedirectUris = { "http://localhost:50309/signout-callback-oidc" },

and also in your MVC client you need to change that too. options.Authority = "http://localhost:5000";
