Monica does not send reminders or stay_in_touch mails

[peetersdaan]

First and foremost thank you guys for creating Monica!

Currently I'm trying to run the Monica Supervisor Apache on my Synology DS418 Play.

php artisan monica:test-email works.
php artisan send:stay_in_touch and php artisan send:reminders do not.

My docker compose:

version: "3.4"

services:
  app:
    build: ./app
    image: monica-app
    depends_on:
      - db
    environment:
      - APP_KEY=**** 
      - DB_HOST=db
      - TZ=Amsterdam/Europe
      - MAIL_MAILER=smtp
      - MAIL_HOST=****
      - MAIL_PORT=****
      - MAIL_ENCRYPTION=****
      - MAIL_USERNAME=****
      - MAIL_PASSWORD=****
      - MAIL_FROM_ADDRESS=****
      - MAIL_FROM_NAME="Monica Personal CRM"
      - APP_URL=****
      - QUEUE_CONNECTION=database
      - PUID=1026
      - GUID=101
    ports:
      - 8080:80
    volumes:
      - ****:/var/www/html/storage
    restart: always

  db:
    image: mysql:5.7
    environment:
      - MYSQL_RANDOM_ROOT_PASSWORD=true
      - MYSQL_DATABASE=monica
      - MYSQL_USER=homestead
      - MYSQL_PASSWORD=secret
    volumes:
      - ****:/var/lib/mysql
    restart: always

How can I fix this issue?

The issue seems to be resolved; the stay in touch and reminder e-mails seem to be working, even though the php artisan send:stay_in_touch and php artisan send:reminders do not.
