- Plesk Onyx
- DNSSEC extension is installed and corresponding DS records are added for domain example.com in Domains > example.com > DNS Settings
- The online-tool dnscheck.pingdom.com shows the following warning message for domain example.com:
CONFIG_TEXT: Broken chain of trust DNSKEY found at child, but no DS was found at parent.
The chain of trust is not complete: the registrar requests
parent zone for domain example.com to sign DS records with their own keys to complete chains of trust, but no DS record was found on the parent-side servers.
Contact the registrar to configure DNSSEC on their side.
