"The service of SimpleDNS Plus v. 126.96.36.199 was erroneously detected as “Not Activated”."
- Plesk Onyx 17.5.3 23 March 2017 (Windows)
Simple DNS Plus 188.8.131.52 becomes unavailable after Plesk upgrade to Onyx 17.0.17.
This is Plesk bug with ID #PPPM-5678 which was fixed in Plesk Onyx 17.5.3 .
Upgrade to the latest Plesk version .
As a workaround, create an empty
file at the Simple DNS installation folder, for example:
C:\ProgramData\JH Software\Simple DNS Plus\license.xml
Plesk will accept the updated configuration automatically.
