pi-hole ip: 192.168.68.137 (dedicated)
pi-hole is not the DHCP server
only my pc connects to the pi-hole with ip:
ip4: 192.168.68.112
ip4-DNS: 192.168.68.137 (not encrypted)
DNS is manually altered
ip6 is off
doubleclick.net is black listed, just to see if that works
based on your nslookup command, your machine is NOT using pihole (192.168.68.37) as DNS. If you are using Windows try the command ipconfig /all and it will show you your current DNS server. Hopefully a forum developer will give you more details explanation as to why when they look at your debug token.
my ipconfig /all shows the dns is ip-hole....i guess
i see what you think, the 8.8.8.8 in the dnslookup. dunno where that comes from... i investigate further
I had the router DHCP correctly installed, but my wife couldn't work from home anymore. So i changed it back to original settings. BUT my laptop is now the only one i connect (actively) to the pi by manually changed the IP settings (IP still by DHCP but DNS manually).
ipconfig / renew
ipconfig /all shows DNS is pihole (192.168.68.137)
adlist, i didn't change anything there, if you have 1,7M and mine is only 189K, then that is a good place to start looking.
Your above nslookup result has shown the device it was run from was using Google's DNS servers (8.8.8.8).
How did you address that?
EDIT:
Your debug log shows your router to distribute two public DNS servers:
*** [ DIAGNOSING ]: Discovering active DHCP servers (takes 10 seconds)
Scanning all your interfaces for DHCP servers
* Received 300 bytes from eth0:192.168.68.1
Offered IP address: 192.168.68.109

--- end of options ---
I did made groups, like my name and IoT group but didnt place any devices in there yet. i wasn't ready with renaming all the devices (pi isnt my DHCP so names were unknown).
I removed all the groups and placed everything in the default group. but this was yesterday. today it still didnt work.
i think the 8.8.8.8 came from my DHCP server which had a 2nd DNS server .....8.8.8.8 were PI was the first.
I think it was still in the IP cache after i changed it to only one DNS (PI) when i runned dnslookup.
After that i run ipconfig /renew and it showed the correct DNS.
