[Kea-users] New user - can't seem to make my DDNS updates work?

I've tried changing kea d2 (to not use tsig) and knot (updated the acl to not
use tsig) but it seems to be unchanged - no DDNS updates.
I've tried using knsupdate without tsig and it worked as expected.
I've double checked the documentation for my verson (d2 is 1.6.2) and these
are the supported RFCs:
* Secret Key Transaction Authentication for DNS (TSIG), _RFC 2845_
Dynamic Updates in the Domain Name System (DNS UPDATE), _RFC 2136_
* Resolution of Fully Qualified Domain Name (FQDN) Conflicts among Dynamic
Host Configuration Protocol (DHCP) Clients, _RFC 4703_
* A DNS Resource Record (RR) for Encoding Dynamic Host Configuration Protocol
(DHCP) Information (DHCID RR), _RFC 4701_
Could it be something else - like the fact that my Knot authoritative server
is running on a non-standard port? Or that I have an unbound instance running
at port 53, which forwards requests either to Knot (for local zones) or to
pihole (running in a container) which forwards the requests which aren't ads.
Happy new year btw!
