It is weird. The Support tool shows that the following command returns an empty output:
Running: ps aux | grep 'apache\|mysql\|nginx\|/opt/bitnami'
That means that your services are not running. Could you please execute the following command and share the result with us?
sudo /opt/bitnami/ctlscript.sh restart
sudo /opt/bitnami/ctlscript.sh status
After that, if every service is running and you continue facing issues, you should try to access MySQL console manually with the user (bn_wordpress) and the password in your
sudo /opt/bitnami/mysql/bin/mysql -ubn-wordpress -p
