Docker + Wordpress: styles, scripts, images are not loading in my theme

Question

I'm trying to figure out, why my assets like CSS, JS and images are not loading in my theme when running installation on Docker.

Here's my docker-compose.yml

version: "3.3"
services:
  db:
    image: mysql:8
    container_name: blogpn_mysql
    restart: always
    command: "--default-authentication-plugin=mysql_native_password"
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: wpdb
      MYSQL_USER: user
      MYSQL_PASSWORD: password
    volumes:
      - db_data:/var/lib/mysql
    networks:
      - blogpn_network
  wordpress:
    image: wordpress:latest
    container_name: blogpn_wordpress
    restart: always
    volumes:
      - ./wp-content/themes:/var/www/html/wp-content/themes
      - ./uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_NAME: wpdb
      WORDPRESS_DB_USER: user
      WORDPRESS_DB_PASSWORD: password
    ports:
      - 8211:80
      - 443:443
    depends_on:
      - db
    networks:
      - blogpn_network
  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    container_name: blogpn_phpmyadmin
    restart: always
    ports:
      - 3333:80
    environment:
      PMA_HOST: db
      MYSQL_ROOT_PASSWORD: password
volumes:
  db_data: {}
networks:
  blogpn_network: {}

For the files like CSS and JS I'm getting network error 500 (the URL for styles is http://localhost:8211/wp-content/themes/mytheme/style.css), and for images network error 404. I'm not sure what I'm missing.
