I have setup pi hole and got it working. (nslookup responds to standard domains and blocks for example flurry.com)
However, when I attempt to run an adblock tester in my windows device's browser, as well as using my phone, they score about 65%. When trying the same tests directly from a browser on my raspberry pi, it scores 100%. I do not understand why there should be such a noticeable difference.
I have entered my RPI ip address manually into both fields in DHCP lease settings on my router. Only RPI ip is shown under DNS servers when doing ipconfig /all.
I have tried enabling and disabling secure DNS both on my device and per browser. It always ends up around 60% blocked on the blocker tests.
