If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the Community Help category.
Expected Behaviour:
I would expect most ads to be blocked. I added many extra block lists -- the dashboard shows 285,000 domains blocked.
Actual Behaviour:
Hardly anything gets blocked. My average block rate is less than 2%. I tried Test Ad Block - Toolz but it returned only 3% blocking. I'm pretty sure I set everything up OK, but the block rate is low; I'm seeing many ads.
This is running on a Raspberry Pi 4B. The Pi Hole IP address is 192.168.0.10 (fixed IP). I've set the primary DNS address to 192.168.0.10 in the DHCP section of my router.
The Raspberry Pi is running Debian 12, but on installation I get messages saying Debian 12 is not supported. I skipped the OS check and it seems to work OK -- except for no blocking. I read somewhere that permitting IPv6 could cause this error so I disabled IPv6 with nmtui, but it still gives the same message.
TIA for the help
