- Plesk Multi Server
Plesk Multiserver DNS Template not applying to service nodes if it has an MX record with priority 0:
PLESK_INFO: ERR Some fields are empty or contain an improper value
The issue is caused by the Plesk Multi Server bug with ID #EXTPMS-1374. It will be fixed in the upcoming product updates.
As a workaround, change the MX record priority to 5 or higher.
