Pihole not blocking a domain

[piholin]

Newly set up pihole on a pi3. Everything is up to date and Im running unbound behind it as well. Everything is being blocked except for one domain and it's subdomains - applovin.com. The domain is in several of my blocklists including https://blocklistproject.github.io/Lists/ads.txt and I've even added it into manual blocklists, but it keeps getting resolved.

• Pi-hole [v5.15.5]
• FTL [v5.21]
• Web Interface [v5.18.4]

restarted DNS to flush cache, and it's still pulling it back:
raspberrypi:~ $ sudo pihole restartdns
[✓] Restarting DNS server
raspberrypi:~ $ nslookup ms.applovin.com 127.0.0.1
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
Name: ms.applovin.com
Address: 34.149.108.182
Name: ms.applovin.com
Address: 2600:1901:0:a285::

Other blocked hosts get the correct 0.0.0.0
nslookup events.gfe.nvidia.com 127.0.0.1
Server: 127.0.0.1
Address: 127.0.0.1#53

Name: events.gfe.nvidia.com
Address: 0.0.0.0
Name: events.gfe.nvidia.com
Address: ::

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or do it through the Web interface:

Your debug log shows you've explicitly exempted that specific domain and its subdomains from blocking:

*** [ DIAGNOSING ]: Domainlist (0/1 = (...), 2/3 = regex white-/blacklist)
 id   type  enabled  group_ids     domain                date_added           date_modified
 ---  ----  -------  ------------  --------------------  -------------------  -------------------

Remove that Regex whitelist entry via Pi-hole's Domain management

OMFG. I thought I put it in as blacklist and not white and must have looked at that screen 43 times. Sorry for wasting your time.

Don't be that harsh to yourself - sometimes, a second pair of eyes comes in handy.

Next time, you know you could consider to create and check the debug log to help you help yourself (in case you missed it, that's stored in /var/log/pihole/pihole_debug.log).
And if my findings helped you in the end, the time was certainly not wasted.
