After disabling DHCP from router all devices should be getting there IP from pi-hole
I had to reinstall raspberry pi from v10 - v12. I restored my pi-hole backup and now every 24 hours all my devices lose DHCP lease. The raspberry pi has a static ip and has been added to the DHCP configuration. What am i doing wrong?

How exactly did you configure your RPi's OS for a static IP?
i used this command:
nmcli connection modify "Wired connection 1"
ipv4.addresses 192.168.1.237/24
ipv4.gateway 192.168.1.1
ipv4.dns "1.1.1.1 8.8.8.8"
ipv4.method manual
Does below one says the ipv4.method is configured "manual"?
nmcli -t -f name con show --active | xargs -d '\n' -n 1 nmcli -p -f ipv4.method,ipv4.dns connection show
It will also show other profiles that are active that might borg your setup.
Dont mind the "lo" profile!
Thats for the loopback interface named lo:
$ ip -br link show lo
lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
Above ipv4.dns differs from below?
You could inspect the logs stored in below folder at the timestamp when this happens:
/var/log/pihole/
Look for lines that have dnsmasq-dhcp in them.
Or inspect the systemd journal for warnings/errors etc for the current --boot:
sudo journalctl --full --no-hostname --catalog --priority warning --boot
Or two boots back (-2):
sudo journalctl --full --no-hostname --catalog --priority warning --boot -2
Or --follow the journal live:
sudo journalctl --full --no-hostname --catalog --priority warning --follow
List boots in the journals:
sudo journalctl --list-boots
ok so it looks like this was an issue with my apple tv see here for more Why is my 2021 Apple TV 4K sending ICMPv6… - Apple Community
TL;DR apple tv was sending ICMPv6 router advertisements, i used
echo "net.ipv6.conf.enxb827eb5ac6b4.accept_ra = 0" | sudo tee -a /etc/sysctl.conf
the issue stopped and i didnt get disconnected last night. no idea why this didnt happen in raspberry pi 10 or pihole 5 or maybe a combination of both. thanks for the help though
Let us know in a couple of days if this fixed it permanently so we can mark this as "solved" for others that stumble on this thread?
