Wordpress is not loading resources

After installing wordpress via the following docker-compose file found at the compose website. I use nginx as a reverse proxy to the external container port. I have used certbot to enable ssl on the website by generating a certificate and the redirects.

The problem I have is that no css or js is loading whatsoever.

How do I configure SSL in such a way that wordpress is still loading the right resources?

Edit:

Added the compose file below.

version: '3.3'

services:
   db:
     image: mysql:5.7
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       WORDPRESS_DB_NAME: wordpress
volumes:
    db_data: {}
