Hi
Thanks for your reply.
Indeed I had seen that a file adguardhome was still hanging around in /etc/dnsmasq.d/ I had deleted it but it still didn’t work (but it’s true that I hadn’t restarted the dnsmasq service).
I finally found the solution at this address: Pihole doesn't receive queries from devices on local network - #16 by deHakkelaar - Help - Pi-hole Userspace
After typing this command, it works again:
pihole -a -i single
I think it corresponds to settings → DNS → “Respond only on interface eno1”.
But that doesn’t explain why changing this option in the GUI doesn’t work…
