False Positive on keinbockaufnazis.de with all content blocker

[failxontour]

Tried reporting upstream already?

• I have attempted already, but to no avail.

What are the desired URLs to be unblocked?

Using the all.dns.mullvad.net setting in Chromium based browsers gets me the site
keinbockaufnazis.de blocked but I don't see why?

In extended content blocking i can reach the site. There is no gambling or explicit adult content here.
This is a organisational site dedicated against neonazis located in germany.

As far as I can tell this only affects the domain.

Hello failxontour.

I've looked into this briefly and it's not in any of our blocklists. It seems to be intermittent SERVFAIL issues with the domain:

# dig keinbockaufnazis.de

; <<>> DiG 9.18.39-0ubuntu0.22.04.2-Ubuntu <<>> keinbockaufnazis.de
;; global options: +cmd
;; Got answer:

But here we can see it working fine:

# dig @dns.mullvad.net keinbockaufnazis.de +https
