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.
Your very welcome, I do support a SaaS system for the UK NHS. So I do have a bit of networking skills, that and I self host things both at home and in OVH.
If you have your pi zero setup with a static ip, you should find things work all day every day now.
Just remember that every day is a school day, even for experienced sysadmins.
