I keep getting the following error between postman and IdentityServer 4

- In my Identity Server Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddIdentityServer(
options => {
options.Events.RaiseErrorEvents = true;
options.Events.RaiseInformationEvents = true;
options.Events.RaiseFailureEvents = true;
options.Events.RaiseSuccessEvents = true;
options.IssuerUri = "http://localhost:5000";
}
)
.AddDeveloperSigningCredential()
.AddInMemoryApiResources(Config.GetAllApiResources())
.AddInMemoryClients(Config.GetClients())
//.AddInMemoryIdentityResources(Config.GetIdentityResources())
.AddInMemoryApiScopes(Config.GetApiScopes());
}
// 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.UseIdentityServer();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapGet("/", async context =>
{
await context.Response.WriteAsync("Hello World!");
});
});
}
- And here's the core for my API's startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication("Bearer")
.AddIdentityServerAuthentication(options =>
{
options.Authority = "http://localhost:5000";
options.RequireHttpsMetadata = false;
options.ApiName = "MyNumberV2Api";
});
#region AddAuthentication
services.AddDbContext<MyNumberV2.Data.MyNumberV2Context>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
IdentityModelEventSource.ShowPII = true;
services.AddScoped<IAdminUserRepository, AdminUserRepository>();
services.AddCors(options =>
{
options.AddPolicy("Open", builder => builder.AllowAnyOrigin().AllowAnyHeader());
});
services.AddMvcCore();
services.AddControllers();
}
// 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.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseAuthentication();
app.UseCors("Open");
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
Here is my public repo for the full solution code: https://github.com/zachion/blazor-auth
Here is how I generate an auth token in postman:
And here is the body section of my request to get the token where i add the Grant type and Scope.
I get the token from the response and add it to the follow up requests for trying to get to the actual api's controllers.
Here is how I add the auth token in postman. Issuing the token works fine
Here's the complete post man collection I use:

There is 2 issues in your code, I start from easy one to fix:
On your API's startup class, move
app.UseAuthentication();to be beforeapp.UseAuthorization();. Proper order is critical for security. Read more here. Similar issue hereSecond issue is that on API you are asking for audience =
MyNumberV2Apibut if you check your current token on https://jwt.ms/ there is noaudasMyNumberV2Apiin the token. Read more here. To fix this we have two options:2.1. Change API to remove audience validation. To do this on API startup class use
AddJwtBearerinstead ofAddIdentityServerAuthenticationand setValidateAudience = false. After change code would be like this:services.AddAuthentication("Bearer").AddJwtBearer("Bearer", options => { options.Authority = "http://localhost:5000"; options.Audience = "MyNumberV2Api"; options.RequireHttpsMetadata = false; options.TokenValidationParameters = new TokenValidationParameters() { ValidateAudience = false }; });2.2. Add the audience to token. On IdentityServer -
Config.cs, add the scopes to API resource:return new List<ApiResource>() { new ApiResource("MyNumberV2Api","Customer API for MyNumberV2") { Scopes = new []{ "MyNumberV2Api" } }, new ApiResource("ApiOne","Customer API for MyNumberV2"), new ApiResource("ApiTwo","Customer API for MyNumberV2") };After this change, if you regenerate the token there will be a property as
audwith value asMyNumberV2Api. Check the token on https://jwt.ms/
I suggest you to test every thing on http first and then try on https. For http you may need to remove app.UseHttpsRedirection(); in your code and also clean up the launchSettings.json to remove https URLS and make sure "sslPort": 0.
