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.
yeah, your PI zero goes to renew its DHCP lease and cant as its lost its IP and so cant see the DHCP server its running.
I would read up on how to set a debian static IP, that way you know how and your Pi zero will work all the time
Can I just take a moment to say thank you. This is either super tedious for you or a nothing part of your day, but you’ve been helping so much and I’m extremely grateful!
I ended up finding this https://www.liberiangeek.net/2024/02/set-up-static-ip-address-debian-12/
And went with the
nmtuioption. Though one of the screenshots was missing, so ended up double checking with https://www.tecmint.com/nmtui-configure-network-connection/Fingers crossed!
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.
