brand new installation not connecting to database

[l0rddarkf0rce]

The installation process seems to go smoothly until it is time for first run after I run php artisan koel:init --no-assets, I get WARN Cannot connect to the database. Let's set it up. I try to enter the requested information to no avail. When I look at the DB logs I see the following message.

2025-01-24 16:09:32 3 [Warning] Aborted connection 3 to db: 'unconnected' user: 'unauthenticated' host: '172.21.0.3' (This connection closed normally without authentication)

The IP shown is the correct IP for the koel container, so they can see each other. So I am not sure what the problem is at this point. Here is how I create the 2 containers and network.

docker network create --attachable koel-net

docker run -d \
   --name koel-db \
   -e MYSQL_ROOT_PASSWORD='koel' \
   -e MYSQL_DATABASE='koel' \
   -e MYSQL_USER='koel' \
   -e MYSQL_PASSWORD='koel' \
   --restart unless-stopped \
   --network=koel-net \
   -v /data/koel/koel_db:/var/lib/mysql \
   mariadb:10.11

docker run -d \
   --name koel \
   -p 80:80 \
   -e DB_CONNECTION=mysql \
   -e DB_HOST='koel-db' \
   -e DB_DATABASE='koel' \
   -e DB_USERNAME='koel' \
   -e DB_PASSWORD='koel' \
   --network=koel-net \
   -v /share/Music:/music \
   -v /data/koel/covers:/var/www/html/public/img/covers \
   -v /data/koel/search_index:/var/www/html/storage/search-indexes \
   --restart unless-stopped \
   phanan/koel

Right after that I type docker exec --user www-data -it koel bash to go into the container and run the php artisan koel:init --no-assets command to initialize and create the APP_KEY.

If I try to connect to the GUI interface on koel I see the following error message...

SQLSTATE[HY000] [1130] Host '172.21.0.3' is not allowed to connect to this MariaDB server (Connection: mysql, SQL: select * from `licenses` order by `created_at` desc limit 1)

Thanks in advance for any help!
