Hey Steven,

It seems like you setup correctly already but to be sure you can set your email address into your cron mail section, I believe you will see this section on the cronjob configuration page.

Once you added this, you can temporary modify to */1 1 minute process your cronjob, so after 1 or 2 minute, try check your mailbox and see whether your server did send you how the cronjob response.

When you check it, it show something like /bin/wget not found warning, perhaps you can try add this /usr/bin/wget into your existing cronjob command and see how it goes.

If the issue still persists, perhaps you can update your Cpanel access at your first post so we can better have a check.
