Cause

System utilities (curl, wget, php, etc.) are not available for the subscription user.

Resolution

Solution I:

Recreate the scheduled task from under a root user at Tools & Settings > Scheduled Tasks:

• Task type: Run a command
• Command: /opt/plesk/php/8.2/bin/php -q /var/www/vhosts/example.com/httpdocs/whmcs/crons/cron.php
• System user: root

OR

• Task type: Run a PHP script
• Script path: /var/www/vhosts/example.com/httpdocs/whmcs/crons/cron.php
• Use PHP version: select a required version
• System user: root

Solution II:

Provide the system user john_doe with access to the server over SSH (for example, /bin/bash) at Domains > example.com > Hosting.

Solution III:

Change the crontab shell for scheduled tasks to /bin/bash at Tools & Settings > Scheduled Tasks > Settings.

Solution IV:

If access to the server over shell is set to /bin/bash (chrooted), add a required utility to chrooted environment.
