Kea D2 -DDNS fails in updating the Power DNS records.
Iam using Kea 1.6.2 and PowerDNS 4.0.8
Initial condition: For a device there is already a DNS entry in the DNS made by DHCP (this is successful). Now when a new IP is assigned to same device Iam seeing this error . DHCP has given a new IP for the device but the DNS entry is not updated.
The DHCID is autogenerated by the Kea DHCP server.
I see the following error code in Kea D2 DDNS update request 2020-06-18T17:54:03.481895214Z 2020-06-18 17:54:03.481 ERROR [kea-dhcp-ddns.d2-to-dns/64] DHCP_DDNS_FORWARD_REPLACE_REJECTED DNS Request ID 000001B13A3A0E8D7BA3C3844FEBD743E5262E8B35B9CBD37FB12A405586E8FA6F89EF: Server, 188.8.131.52 port:53, rejected a DNS update request to replace the address mapping for FQDN, hang-q6v8-fvcs.abc.net., with an RCODE: 8
And the corresponding DNS logs Jun 18 17:53:54 UPDATE (42311) from 184.108.40.206 for abc.net: Failed PreRequisites check, returning 6 Jun 18 17:53:54 UPDATE (28718) from 220.127.116.11 for abc.net: Failed PreRequisites check, returning NXRRSet
Can you please tell why this is happening and what I have to do to fix this issue.
