Issue with email alert when folder is shared?

Currently trying to configure email alerts when user tries to share a folder
I get the email alert when i test the smtp settings with no issue
then i tried running the cron manually
running next cloud 21.0.3

root@cloud:~# /usr/bin/php -f /var/www/nextcloud/cron.php
Console has to be executed with the user that owns the file config/config.php
Current user id: 0
Owner id of config.php: 33

but still no alert not sure if im missed something?



Thank you
