Email Invite not working

[gader-abdollah]

The player fails to send email invites to users

To reproduce

1. Go to Users > Invite
2. Enter a single email such as abc@example.com
3. Leave admin role unchecked
4. See Unknown error

Environment

• Koel version v6.12.1
• Server OS: Ubuntu via Portainer
• Laptop OS: Fedora 39
• Browser: Firefox 124.0.1 (64-bit)
• PHP version 8.1.8

Additional context
I did not test with multiple emails as I only need to send an invite to a single person.
Here is the stack I used:

version: '3'

services:
  koel:
    image: phanan/koel
    restart: always
    depends_on:
      - database
    ports:
      - some_port:80
    environment:
      - FORCE_HTTPS=true
      - SPOTIFY_CLIENT_ID=ehem
      - SPOTIFY_CLIENT_SECRET=ehem
      - YOUTUBE_API_KEY=ehem
      - LASTFM_API_KEY=scusi
      - LASTFM_API_SECRET=eeeeeeeeeh_nope
      - DB_CONNECTION=*****
      - DB_HOST=******
      - DB_USERNAME=*****
      - DB_PASSWORD=*******
      - DB_DATABASE=******
    volumes:
      - music:/music
      - covers:/var/www/html/public/img/covers
      - search_index:/var/www/html/storage/search-indexes


  database:
    image: mariadb:10.11
    restart: always
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=*****
      - MYSQL_DATABASE=*****
      - MYSQL_USER=*****
      - MYSQL_PASSWORD=******

volumes:
  db:
    driver: local
  music:
    driver: local
  covers:
    driver: local
  search_index:
    driver: local

Once it was up, I ran these commands:

php artisan koel:init --no-assets && apt update && apt dist-upgrade -y && apt install inotify-tools -y
echo '#!/bin/bash

MEDIA_PATH=/music

inotifywait -rme move,close_write,delete --format "%e %w%f" $MEDIA_PATH | while read file; do
  php artisan koel:sync "${file}"
done' > watch
chmod +x watch && ./watch & disown -h

This is the initial setup with watch setup.

I have no idea why it is not working. Maybe it cannot send emails in general ?
Anyway, it is also running behind Nginx Proxy Manager but the connection is coming through no problem...
Is there a need to open more ports for email sending maybe ??

Hi, i was having the same issue, let me share what i did to fix it:

in the .env file take a look at this lines:

# The following settings are for Koel to send emails, for example to send user invitations and reset passwords. MAIL_FROM_ADDRESS="hello@example.com" MAIL_FROM_NAME="${APP_NAME}" MAIL_MAILER=smtp MAIL_HOST=mailhog MAIL_PORT=1025 MAIL_USERNAME=null MAIL_PASSWORD=null MAIL_ENCRYPTION=null

make sure you complete that part, i used my websites email, created music@mywebsite.com, added a password and used SMTP . i added those details to the file and that fixed my error
