ACME Companion not running at startup

[SyphonxZA]

I am using nginx-proxy and nginx-proxy-acme (along with other services). All services run at startup except for nginx-proxy-acme. To get it running I need to manually run docker compose up on my server (Debian 11). It then runs fine and renews my certs, however 3 months later it becomes an issue again as the certs expire because the service never runs.

Is this the default behaviour? I can't find anything in the docs to explain why it does not run at startup.

Below is my compose file:

 version: "2.4"
 
services:
  nginx-proxy:
    image: nginxproxy/nginx-proxy
    container_name: nginx-proxy
    environment:
    - PUID=${PUID}
    - PGID=${PGID}
    - TZ=${TZ}
    volumes:
    - /var/run/docker.sock:/tmp/docker.sock:ro
    - ${USER_DIR}/.docker/nginx/certs:/etc/nginx/certs:rw
    - ${USER_DIR}/.docker/nginx/vhost.d:/etc/nginx/vhost.d
    - ${USER_DIR}/.docker/nginx/html:/usr/share/nginx/html
    - ${USER_DIR}/.docker/nginx/conf:/etc/nginx/conf.d
    ports:
    - 80:80
    - 443:443
    restart: always
  nginx-acme:
    image: nginxproxy/acme-companion
    container_name: nginx-proxy-acme
    environment:
    - PUID=${PUID}
    - PGID=${PGID}
    - TZ=${TZ}
    - DEFAULT_EMAIL=${EMAIL}
    volumes_from:
    - nginx-proxy
    volumes:
    - /var/run/docker.sock:/var/run/docker.sock:ro
    - ${USER_DIR}/.docker/nginx/certs:/etc/nginx/certs:rw
    - ${USER_DIR}/.docker/nginx/vhost.d:/etc/nginx/vhost.d
    - ${USER_DIR}/.docker/nginx/html:/usr/share/nginx/html
    - ${USER_DIR}/.docker/nginx/acme:/etc/acme.sh
    restart: always
