Hello, I'm trying to install Piwigo using Docker but I'm having problems installing.

After accessing the port where I started the piwigo container, always after filling the database and user data, when clicking to start the installation, the following error occurs:

This page isn't working0.0.0.0 is currently unable to handle this request.
HTTP ERROR 500

I already tried to install by uploading separate containers for piwigo and the piwigo database, and with docker-compose, my last attempt was with:

version: '3'

services:
   db:
     image: lscr.io/linuxserver/mariadb:latest
     container_name: piwigo_db
     restart: unless-stopped
     environment:
       - PUID=1002
       - PGID=1002
       - TZ=America/Sao_Paulo
       - MYSQL_ROOT_PASSWORD=ZZZ
       - MYSQL_DATABASE=piwigo_db
       - MYSQL_USER=ZZZ
       - MYSQL_PASSWORD=ZZZ
     volumes:
       - /media/Courses/piwigo/database:/config

   piwigo:
     image: lscr.io/linuxserver/piwigo:latest
     container_name: piwigo_web
     restart: unless-stopped
     depends_on:
       - db
     environment:
       - PUID=1000
       - PGID=1000
       - TZ=America/Sao_Paulo
     ports:
       - "82:80"
       - "444:443"
     volumes:
       - /media/Courses/piwigo/gallery:/gallery
       - /media/Courses/piwigo/config:/config
       
After uploading the containers, they are running normally, I can confirm this with docker-ps or portainer.
How can I solve it?
