If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx, apache2 or another reverse proxy, or there is some other aspect of your install that is customised) - please use the Community Help category.
Expected Behaviour:
I Use the latest Pi Home on a Raspberry Pi 4 nimmst Network. In the query log I often see
Ib._dns-sd._udp.fritz.box
I put this to my allow list but I didn’t work see this message every day
See screenshots
Actual Behaviour:
Despite the fact that the address is allowed, it is blocked
But as others would match, that would suggest that queries may not have been blocked by Pi-hole, but by its upstream - in case of lb._dns-sd._udp.fritz.box, that would have been your Fritzbox router, as that is handling *.fritz.box.
Let's take a closer look at some of those PTR requests during the last 10 days. Run from your Pi-hole machine, please share the output of:
sudo pihole-FTL sqlite3 --header --column /etc/pihole/pihole-FTL.db \
"SELECT reply_type, status, forward FROM queries \
WHERE type = 6 AND domain = 'lb._dns-sd._udp.fritz.box' \
AND timestamp > strftime('%s','now','-10 days') LIMIT 10;"
A status of 8 confirms that lb._dns-sd._udp.fritz.box is blocked by Pi-hole's upstream (see Supported status types from Query Database - Pi-hole documentation):

Pi-hole's web UI should also list respective query log entries as (Blocked, external) when hovering over the blocked icon or inspecting an entry's details.
