Not enough ads blocked

Expected Behaviour:

Expecting to have much more than 5% ads blocked while using a lot of lists :

  • Raspberry Pi OS 64bits
  • Raspberry Pi 4
  • Using dnscrypt-proxy

Actual Behaviour:

I'm currently having around 5% Ads blocked, a few months ago it was much much more with less ad lists, but I had to change ISP provider and my Sd Card for my RPI, so I did a fresh install and disabled DHCP from the provider's router and activated DHCP from Pi-hole, I also set the static IP's as it should, but I still get a lot of ads.

Debug Token:

The 5% percentage doesn't mean "only 5% of all ads were blocked and 95% of ads are shown".

The percentage means: only 5% of all DNS requests were blocked by Pi-hole and the rest was not considered ads.

Blocking percentages can be expected to fluctuate over time.
By themselves, they wouldn't be a reliable indication.

Did the number of DNS requests also drop significantly?

Together, that could suggest that DNS requests may be going elsewhere, by-passing Pi-hole.

Your debug log shows your Pi-hole host device to have full IPv6 connectivity.
Perhaps your router is advertising an non-Pi-hole IPv6 address as DNS server?

It seems that my ISP box doesn't forward everything to Pi-hole ... I'm trying to understand why and how I can fix that.
