- Plesk Onyx
Cron job on Plesk server that fetches a URL sends an error email when URL returns an error with the status code 204.
HTL response code 204 means "success, with no content". Plesk considers this code as an error code and thus the email notification is being sent. This is considered as Plesk bug with ID #PPPM-9565 which will be fixed in next product updates.
As a workaround, disable the email notifications in Plesk for the affected Cron job.
- Log into Plesk UI.
- Open Tools & Settings > Scheduled tasls > click on affected name > set Notify option as "Do not notify".
