Not to draw attention away of @SweeTiPie, but I am also unable to generate a debug code.
can I post my results for
pihole-FTL dhcp-discover
and
ls -la /etc/dnsmasq.d/
?
all my versions are the same except for php for which i‘m on 7.3.29 - and i‘m running pi-hole on a Raspberry Pi 4, not sure if it helps to know that
