Re: How to resolve Unbound causing N/A Reply for certain domains?

I've been using Pi-Hole on my RPi4 for several years now and a couple
months ago I decided to give Unbound a go. I followed the instructions
as described in https://docs.pi-hole.net/guides/dns/unbound/ and set my
DNS in Pi-Hole to 127.0.0.1#5335 (DNSSEC is unchecked). Everything seems
to work fine, but then I noticed certain domains result in Server Not
Found and the Query Log shows an N/A Reply for these sites.

That problem seems to be solved. I forgot to mention I was (am) working
behind a double NAT. My ISP's modem (crippled; very few options) and my
own router (more options). Yesterday, I tested a fresh install
(Bookworm, Pi-Hole & Unbound) on an RPi4 on a network with the same
modem (same ISP), but directly connected to the modem. Those domains
could be reached without a problem.

I now have some options :switching my ISP's modem with a Fritz!Box or
switching the modem with another one my ISP offers, one that can be used
in Bridge Mode. Unfortunately, I just found out my router (TP-Link
Archer AX55) that I just bought doesn't support Bridge Mode. So I would
have to buy a new router, an AP with at least one extra Ethernet port
and a 30 m cable.

I decided to give this a pass and have chosen Cloudflare (DNSSEC) to be
Pi-Hole's DNS. Too bad about Unbound... (My ISP blocks port 53, so
portforwarding wasn't an option either.)
