Unable to add forward map from REFUSED

[caplam]

Hello,
i noticed for a few weeks (not sure when it started) i have messages in isc dhcp log file:
Unable to add forward map from hostname.domain.tld to 192.168.2.42: REFUSED
i have the message for all hostnames (with static or dynamic mapping)

However when i ping or nslookup the hostname the answer is correct.
I read about blocklist which could be problematic and i disabled all blocklists.
unbound seems to be running:
