I have the Pi-Hole acting as the DHCP server and DNS server too and this works fine for 23 hours and then it flops and I don’t understand why.
Basically after 24 hours, all devices just disconnect from the router and when I try and reconnect them, they say they’re unable to get an IP address.
But before they drop connection, they all report the DNS server as the Pi-Hole.
If I change my DHCP to static and connect to my router, I see that the Pi-Hole is still connected with its static IP just fine.
If I factory reset the router and then add the same SSID and password, the Pi-Hole automatically reconnects and then all devices can reconnect again, so I’m unsure what the issue is.
Can someone break this down. I feel stupid for not understanding what’s happening here.
When it goes tomorrow around 11 o’clock, I’ll SSH in and report back.
Nope, when I log into the VM router admin page, DHCP is still off.
Yep, the Pi-Hole is hosted on a Pi-Hole Zero 2 W, so it’s WiFi only. I thought setting the DHCP lease time on the Pi-Hole to a year would solve the issue, but nope, after 24 hours, everything disconnects and the only way to get them to reconnect is to factory reset the router.
I would read up on static ip on the pi zero, not via DHCP. That might sort your issue
