  • How are you testing this? More and more services and applications are moving to DoH and similar DNS resolution methods that are more secure and private. Firefox is probably the most significant one to recently switch to using DoH for DNS resolution. – Nmath Nov 21 '20 at 23:24
  • Firefox is currently hosting an open comment period about the worldwide rollout of DoH. Perhaps you can add your voice to let them know that you would still like a DNS based method for content blocking. Personally, I've suggested mozilla to work with the pihole team to make this a reality. See: https://blog.mozilla.org/netpolicy/2020/11/18/doh-comment-period-2020/ – Nmath Nov 21 '20 at 23:27
  • 'sudo chattr +i /etc/resolv.conf' and reboot should preserve your edits – pierrely Nov 23 '20 at 05:02
  • OK. It looks like chattr have "done the job". I am really happy with pihole so for now it need to be like that. Thanks for Your time and help to all of You. To someone who has the same problem. Poblem was with resolved To switch off resolver> sudo systemctl disable systemd-resolved.service sudo system stop systemd-resolved.service and at the end sudo nano /etc/resolv.conf --put your dns ip sudo chattr +i /etc/resolv.conf Solution is not perfect but it works (for now ) – Norbert Bolik Nov 23 '20 at 15:34
