Enabling DB (external MariaDB) after installation

[jorcat]

I've installed vaultwarden following this script
https://community-scripts.github.io/ProxmoxVE/scripts?id=vaultwarden
in Proxmox (Alpine Linux)

I've modified the file /etc/conf.d/vaultwarden (inside the LXC)

export DATABASE_URL=mysql://vaultwarden:****@192.168.1.50:3306/vaultwarden?charset=utf8&ssl=true
export DATABASE_TIMEOUT=30
export DATABASE_MAX_CONNS=10
export DATABASE_CONN_INIT=""

I've created the DB in the MariaDB, and also the user vaultwarden.

After restarting the LXC is not connecting to the DB, and I don't know where are the logs.

Anyone else has this issue?
