Note: This article has the reference to the issue with the fix available:
- #PPPM-6420 "If the name of a customer’s subscription was the same as the server’s hostname,
the customer could not save changes in the domain hosting settings."
- Plesk Onyx 17.5.3 Update 9 13 June 2017
It is not possible to change hosting settings for the domain example.com:
PLESK_ERROR: This domain name is the same as hostname of the server.
The website's domain name like example.com.
The domains belongs to the customer and it the same as server's hostname
This is a Plesk bug #PPPM-6420. It will be fixed in future Plesk releases.
As a workaround, consider to change the domain name or server's hostname.
