Сбой аутентификации ASP.NET Core 2.0 при запуске через Nginx в Unix

Question

Я создал простое базовое веб-приложение ASP.NET (в виде API), и все отлично работает в Windows.Я пытаюсь запустить его через обратный прокси-сервер на Nginx, и приложение завершается с ошибкой аутентификации:

Работает нормально, напрямую через Kestral через порт 5000 (выглядит так):

Я перепробовал все предложения о различных способах настройки службы аутентификации, текущий класс запуска выглядит следующим образом:

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {

            services.AddMvc();
            services.AddAuthentication(Microsoft.AspNetCore.Server.HttpSys.HttpSysDefaults.AuthenticationScheme);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseForwardedHeaders(new ForwardedHeadersOptions
            {
                ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
            });

            app.UseAuthentication();

            app.UseMvc(routes =>
            {
                routes.MapRoute("default", "{controller=Ite}/{action=Execute}");
            });
        }
    }

Текущая конфигурация nginx выглядит следующим образом:

server {
     listen 80;
     server_name ite.photosite.shop;

     access_log  /var/log/nginx/ite-photosite-access.log;
     error_log /var/log/nginx/ite-photosite-error.log notice;


     location / {
         proxy_pass http://127.0.0.1:5000;
         proxy_http_version 1.1;
         proxy_set_header   Upgrade $http_upgrade;
         proxy_set_header   Connection keep-alive;
         proxy_set_header   Host $http_host;
         proxy_cache_bypass $http_upgrade;
     }
 }

Что я взял из этой инструкции по развертыванию на linux .Несмотря на то, что в настоящее время я не выполняю аутентификацию, я также добавил (и удалил, и попробовал каждую комбинацию):

        app.UseForwardedHeaders(new ForwardedHeadersOptions
        {
            ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
        });

В разделе конфигурации.

Каждый раз, когда я получаю одну и ту же ошибку.

Редактировать - добавлен класс запуска
