Pihole not disabling ads on Raspberry Pi

Help
1

Expected Behaviour:

Pihole should be blocking ads.

Actual Behaviour:

On a Windows PC I am looking at Test your ad blocker (in a few simple steps) - Ads-blocker.com and all the ads are getting through. Ads are also getting through on Andriod phone games.

I recently changed my routers to Nokia Beacons. Pihole stopped working and so I did a clean reinstall of the Raspberry Pi OS and pihole. But Pihole is still not blocking ads.

I notice that resolv.conf keeps overwriting 127.0.0.1 with 8.8.8.8 every few seconds. I don't know what's doing it, but the file says Generated by resolvconf. Inside those few seconds, the browser is able to resolve pi.hole/admin, but once resolv.conf gets overwritten, I can't get to the pihole admin page unless I use Raspberry Pi IP address.

I've disabled DHCP under LAN on the router admin page and Primary DNS is a blank.

On the Windows PC, ipconfig /all returns this for the wifi:

Your debug log shows a problem - the engine of Pi-hole is not running:

*** [ DIAGNOSING ]: Pi-hole processes
[✓] lighttpd daemon is active
[✗] pihole-FTL daemon is failed

What are the outputs of these commands from the Pi terminal:

sudo netstat -nltup | grep 'Proto\|:53 \|:5053 \|:5353 \|:5335 \|:8953 \|:67 \|:80 \|:471'

sudo service pihole-FTL status

You have provided a DNS server other than Pi-hole, and the DNS queries are bypassing Pi-hole.

DNS Servers . . . . . . . . . . . : fe80::1%3
                                    192.168.0.143
                                    1.1.1.1

Your Pi-hole is at IPV4_ADDRESS=192.168.18.15/24, and none of these DNS servers match that IP.

Here are the results:

I've disabled DHCP on LAN on router, and left the DNS field blank. But this Windows PC is not going to the pihole DNS.

Run the following commands and post the output of the last two:

sudo service pihole-FTL restart

cat /var/log/pihole-FTL.log | tail -n75

sudo service pihole-FTL status
