Hi Bjoern,
Try enabling the 'debug' log level to see unauthorized requests.
Is it the same with ISC's nsupdate?
Btw, what is your version of Knot DNS?

Hi,
I'm using a script to dynamically update an IPv4. After some time, the

domain='home.schafweide.org'
knsupdate -y "${KNOT_KEY}" <<EOF

update delete $domain 60 A
update add $domain 60 A $1
send
quit

After "systemctl restart knot" the update just runs fine.
I'm wondering what's wrong there.
Regards
Bjoern
