I'm aware that it says i'm unauthorized, but i dont know where to give me authorisation besides the OpenID section on my WHMCS Admin site.

HI! I've tried integrating WHMCS with my blazor project. My Startup.cs is the following: namespace ClientSite { public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } public void ConfigureServices(IServiceCollection services) { services.AddRazorPages(); services.AddServerSideBlazor(); services.AddSingleton<WeatherForecastService>(); IdentityModelEventSource.ShowPII = true; services.AddAuthentication(options => { options.DefaultScheme = "Cookies"; options.DefaultChallengeScheme = "oidc"; }) .AddCookie("Cookies") .AddOpenIdConnect("oidc", options => { options.Authority = "https://domain/oauth/openid-configuration.php"; options.ClientId = "xxxxxxxxxxxx"; // 75 seconds options.ClientSecret = "xxxxxxxxxxxxxxxx"; options.TokenValidationParameters = new TokenValidationParameters { IssuerSigningKeyResolver = (token, securityToken, kid, parameters) => { var client = new HttpClient(); var response = client.GetAsync("https://domain/oauth/certs.php").Result; var responseString = response.Content.ReadAsStringAsync().Result; var keys = JsonConvert.DeserializeObject<JwkListcs>(responseString); return keys.Keys; }, ValidIssuers = new List<string> { "https://domain/" } }; options.ResponseType = "code"; options.SaveTokens = true; options.Configuration = new OpenIdConnectConfiguration { AuthorizationEndpoint = "https://domain/oauth/authorize.php", JwksUri = "https://domain/oauth/certs.php", TokenEndpoint = "https://domain/oauth/token.php", UserInfoEndpoint = "https://domain/oauth/userinfo.php", Issuer = "https://domain", }; options.GetClaimsFromUserInfoEndpoint = true; options.Events = new OpenIdConnectEvents { OnAccessDenied = context => { context.HandleResponse(); context.Response.Redirect("/"); return Task.CompletedTask; } }; }); services.AddSingleton<BlazorServerAuthStateCache>(); services.AddScoped<AuthenticationStateProvider, BlazorServerAuthState>(); } public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseExceptionHandler("/Error"); app.UseHsts(); } app.UseHttpsRedirection(); app.UseStaticFiles(); app.UseAuthentication(); app.UseRouting(); app.UseEndpoints(endpoints => { endpoints.MapBlazorHub(); endpoints.MapFallbackToPage("/_Host"); }); } } } But after logging in and being redirected back to my page, i get this error. (attached image) Does anyone know the solution to this problem? Thanks in advance. - Bikbokken.
