Pi Hole blocking normal domain saying "not found in any blacklist"?

Expected Behaviour

I'm trying to visit one of my domains pi.example.com which points to a tailscale IP address. The domain is not a .local domain like in this post, it's a .world TLD.

I expected the Pi Hole to return the A record that it receives from the upstream DNS

Actual Behaviour:

I get an error page saying access has been denied because the "domain was not found on any blocklists" which makes no sense

Debug Token:

https://tricorder.pi-hole.net/0yOshnfx/

This appears to be the 404 page from lighttpd. Pi-hole is not blocking it, but the request ended up with Lighttpd.

Please run the following command from the Pi terminal and post the output:

nslookup pi.example.com 127.0.0.1

And also post the transactions for this query from /var/log/pihole.log

Hey, thanks for the reply.

I ran that command and get the correct A address that I expect.

pi@raspberrypi:~ $ nslookup pi.example.world 127.0.0.1
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
Name: pi.example.world
Address: my tailscale IP

One thing that might be relevant is that the tailscale IP points to the raspberry pi that is hosting the Pi Hole. But I expect it to load the Pi Hole admin panel not an error page. Maybe it's not recognising the hostname and so it's ignoring the request?

I'm able to connect to a website hosted on a different port on my Pi using that domain name, so it's definitely an issue specifically with the server hosting the Pi Hole admin panel

Only http://pi.hole will automatically redirect to the admin page. If you use anything other than pi.hole then you'll need to go directly to http://<custom>/admin/.

This is a security feature to prevent someone external to your network being able to access the admin page.

Okay thanks, /admin works for me but http://pi.hole does not. That's okay though, thanks for your help
