When I arrived home from work I couldn't connect to my home network.
Pihole is set as DHCP, and I have disabled it on my ISP router.
Android device was showing "IP configuration failure" in the WiFi settings.
Reboot ofnrouter did not help.
Connected laptop via cable to the router and still couldn't connect to either the internet or LAN devices, e.g. the router admin page or pihole.
As a last resort I pulled the plug in the Pi and powered back on...which threw some errors. I've attached some screen grabs.
Managed to get the Pi booted though and access is back.
But I'm trying to diagnose. I suspect it may be an IP conflict, with the same address handed to multiple devices if this is possible?
I suspect this as there seemed to be a mismatch between leases and devices
My pihole admin is now showing no active leases, only the static DHCP leases I assigned. (Fyi, I have all my devices a static IP)
Any tips? Or is Pi and/or SD card borked?
