Stuck with "error accessing config table"

Hi all, I'm trying to give a run with this tool and used Portainer to create a new stack with the config file hereunder:

# from https://github.com/fametec/glpi

version: "3.5"
services:

which is pretty close to the docker-compose.yml you propose. Unfortunately, if the stack deploys smoothly, I just can't access the GUI, getting this "Error accessing config table" error.

Logs of the cron service says:

log_it: (CRON 7) INFO (RANDOM_DELAY will be scaled with factor 50% if used.)

log_it: (CRON 7) INFO (running with inotify support)

log_it: (root 11) CMD (/usr/bin/php -c /etc/php.ini /var/www/html/front/cron.php --forcequeudnotification )

log_it: (root 12) CMD (/usr/bin/php -c /etc/php.ini /var/www/html/front/cron.php )

log_it: (root 13) CMD (/usr/bin/php -c /etc/php.ini /var/www/html/front/cron.php --forcemailgate)

log_it: (root 8) CMDOUT (PHP Warning:  mysqli::real_connect(): (HY000/2002): Connection refused in /var/www/html/inc/dbmysql.class.php on line 185)

log_it: (root 8) CMDOUT (A link to the SQL server could not be established. Please check your configuration.)

log_it: (root 8) CMDOUT (Le serveur Mysql est inaccessible. Vérifiez votre configuration.)

indicating that the DB server is not accessible and I just can't find where I'm wrong... 🤔 DB and GLPI look fine, no error in their logs.

Any helping hand would be welcome!
