Wordpress w.Nginx Proxy Manager - wordpress

Question

I have my WordPress instance setup, connected to the database and functioning perfectly when accessed via the docker host IP and port 2142 (mapped to 80.) I have this in my Nginx Proxy Manager the same way I do for all of my other proxy hosts and get 502 bad gateway (openresty) SSL enabled or Disabled makes no difference.
Compose file:
services:
wordpress:
image: wordpress:latest
volumes:
- wordpress_data:/var/www/html
ports:
- "2142:80"
restart: unless-stopped
environment:
- WORDPRESS_DB_HOST=REDACTED
- WORDPRESS_DB_PASSWORD=REDACTED
- WORDPRESS_DB_USER=REDACTED
- WORDPRESS_DB_NAME=REDACTED
- WORDPRESS_TABLE_PREFIX=REDACTED
volumes:
wordpress_data: {}

I have recently fixed this. This is the code:
version: '3'
services:
landing-db:
container_name: ${CONTAINER_DB_NAME}
image: ${DB-IMAGE:-mariadb}:${DB_VERSION:-latest}
restart: unless-stopped
volumes:
- ${DB_FILES}:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
MYSQL_DATABASE: ${MYSQL_DATABASE}
MYSQL_USER: ${MYSQL_USER}
MYSQL_PASSWORD: ${MYSQL_PASSWORD}
landing-wordpress:
depends_on:
- landing-db
container_name: ${CONTAINER_SITE_NAME}
#image: ${SITE_IMAGE:-wordpress}:${SITE_VERSION:-latest}
build:
context: ${DOCKERFILE_CONTEXT}
dockerfile: ${DOCKERFILE_NAME}
restart: unless-stopped
volumes:
- ${SITE_FILES}:/var/www/html
- ${PHP_INI}:/usr/local/etc/php/conf.d/php.ini
environment:
WORDPRESS_DB_HOST: ${CONTAINER_DB_NAME}
WORDPRESS_DB_NAME: ${MYSQL_DATABASE}
WORDPRESS_DB_USER: ${MYSQL_USER}
WORDPRESS_DB_PASSWORD: ${MYSQL_PASSWORD}
WORDPRESS_TABLE_PREFIX: ${WORDPRESS_TABLE_PREFIX}

landing-nginx:
image: nginx:alpine
container_name: landing-nginx
restart: unless-stopped
volumes:
- ${NGINX_CONFIG}:/etc/nginx/conf.d
#- ${NGINX_MY_INCLUDE_FILES}:/etc/nginx/my_include_files
- ${SITE_FILES}:/var/www/html
expose:
- "80"
#ports:
# - "8080:80"
links:
- landing-wordpress
environment:
- VIRTUAL_HOST=${DOMAIN},www.${DOMAIN}
#- LETSENCRYPT_HOST=${DOMAIN},www.${DOMAIN}
#- LETSENCRYPT_EMAIL=${LETSENCRYPT_EMAIL}
networks:
default:
name: ${NETWORK}
I also have a .env file where everything with ${variable_name} is specified.
I built this with dockerfile:

ENTRYPOINT ["docker-entrypoint.sh"]

The docker file is takes from docker-library. You can search it with name "wordpress".
The secret in this case is "expose: 80". It is the port exposed between containers. This will be added on Nginx proxy manager with: {service-name}:{exposed port of nginx service}.
Do not forget to be on the same network.
