I set up a blazorwasm application, It can work normally locally(OIDC), But if I publish to the server,It does not work with a domain name(if use IP, work normally ) I checked F12 and found GET https://{DOMAIN}/.well-known/openid-configuration 404 (use IP is 200) Are there any settings needed here?

{
services.AddDbContext<ApplicationDbContext>(options =>
options.UseMySQL(
Configuration.GetConnectionString("DefaultConnection")));

        services.AddDatabaseDeveloperPageExceptionFilter();
        services.AddCors(options =>
        {
            options.AddDefaultPolicy(
            builder =>
            {
                builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
            });
        });
        services.AddDefaultIdentity<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
            .AddEntityFrameworkStores<ApplicationDbContext>();

        services.AddIdentityServer()
            .AddApiAuthorization<ApplicationUser, ApplicationDbContext>();

        services.AddAuthentication()
            .AddIdentityServerJwt()
        services.AddControllersWithViews();
        services.AddRazorPages();
    }
