PBA-S DNS Server is shown as not "In Use" on the "Nameservers" page in the Parallels Plesk Automation panel (PPA > Services > DNS Zones > DNS > Name Servers).
Also, the following error appears when I try to change a DNS record through PPA > DNS manager > Select Domain > DNS
Fatal error An unforeseen error occurred. Please contact firstname.lastname@example.org Detail Module: "ServiceManagement", code = "10" Properties: service_id = "2". Message: "Service #2 does not exist.".
Misconfiguration of the DNS service on the Parallels Plesk Automation side.
Register the PBA-S as DNS Server in Parallels Plesk Automation again.
