Kong dashboard behind nginx reverse proxy

Hi, I’ve installed kong with docker behind nginx reverse proxy and I don’t see the dashboard correctly

docker-compose.yml

kong:
    image: kong/kong-gateway:2.8.1.4
    container_name: kong
    restart: always
    healthcheck:
      test: ["CMD", "kong", "health"]
      interval: 10s
      timeout: 10s
      retries: 10
    ports:
      - 80:80
      - 8002:8002
    environment:
      KONG_PROXY_LISTEN: 0.0.0.0:80, 0.0.0.0:443 ssl
      KONG_ADMIN_LISTEN: 0.0.0.0:8001, 0.0.0.0:8444 ssl
      KONG_ADMIN_GUI_URL: "http://localhost:8002"
      KONG_PROXY_ACCESS_LOG: /dev/stdout
      KONG_ADMIN_ACCESS_LOG: /dev/stdout
      KONG_PROXY_ERROR_LOG: /dev/stderr
      KONG_ADMIN_ERROR_LOG: /dev/stderr
    command: "kong start"

nginx configuration:

server {
    listen              443 ssl;
    server_name         kong-dash.example.com;
    ssl_certificate     /etc/nginx/certs/crt.pem;
    ssl_certificate_key /etc/nginx/certs/key.pem;

    location / {
        auth_basic           "Admin area";
        auth_basic_user_file /etc/nginx/.htpasswd;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Host $host:$server_port;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_cookie_path / "/; secure; HttpOnly; SameSite=lax";
        proxy_pass  http://kong:8002/;
    }
}

When i go to https://kong-dash.example.com I see incomplete dashboard:

And into network section, it seems to make a call to port 8444, which of course, is unreachable from the browser:

I don’t understand if the problem is the configuration of nginx or kong

Thanks to anyone who wants to help me
