Someone can help me ?

systemd-resolve is blocking your port 53. You need to disable it.

Try

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved

Note that starting pihole-FTL directly is not recommended

You should always use

sudo service pihole-FTL restart

Hello, thanks for your answer
i do it and it works :
xxx@raspberrypi:~ $ pihole status
[✓] DNS service is running
[✓] Pi-hole blocking is Enabled
xxx@raspberrypi:~ $
And the web interface works now.

Thanks very much
