- Plesk Onyx for Linux
- Plesk Onyx for Windows
Plesk is running behind NAT.
If Tools & Settings > Website Preview Settings > Quick Preview on a domain name in Plesk is used, incorrect A-record for website preview is added to the domain DNS settings.
This is Plesk bug with ID #PPPM-6234 that will be fixed in future updates.
As a workaround, set the correct IP address manually in Subscriptions > example.com > Websites & Domains> DNS Settings of example.com for preview record.
