Unbound SERVFAIL results only

Your new debug log also shows your router is using itself as DNS server.

Look at the dns-server: 192.168.1.1 line:

Edit:
If you are sure you edited the DNS on the correct place, maybe you need to renew the DHCP lease for you Pi-hole device (current lease time is 12h).

You need to set Pi-hole as DNS server on DHCP settings.

Note:
I don't have a device using OpenWRT, so I can't tell what is the correct page.

I tried to disable my DHCP server but I've lost access to my Openwrt router

I'll try to troubleshoot it. I'll learn as I go along. I'm really newbie here.

My Wifi interface if up. But i cannot keep connected. I'm going to test it over LAN.

I'll return as soon as get back access.

Sorry for my absolutely lack of skills.

Have a look at this: https://tricorder.pi-hole.net/GBrv9hxM/

I believe it's done. But we never know :

I saw much better speed response times already. Also, http://pi.hole is now being resolved on any device inside my network.

PS: Spoke too soon. Just received a warning from pi-hole diagnosis:

DNSMASQ_WARN Warning in dnsmasq core:

no address range available for DHCP request via lo

@rdwebdesign I suspect that the last provided token is about to expire.

So, I took the liberty to provide a new one.
