- Plesk for Linux
- Plesk is running behind NAT.
- The website preview URL contains private IP instead of public IP, if Quick Preview on an external domain name is enabled under Tools & Settings > Website Preview. For example: http://domain.com.192.0.2.2.example.com/
This is Plesk bug with ID PPPM-3687 which is planned to be fixed in future product updates.
As a workaround, add the following A record:
CONFIG_TEXT: *.192-0-2-2.example.com A 203.0.113.2
Note: Where 192-0-2-2 matches the internal 192.0.0.2 IP address.
