The issue I am facing: I recently installed pihole and unbound using dietpi installer and checked all the setting after. Everything was working really well and no issues at all for about 1 week. Then my pizero completely became unresponsive and when I navigated to the IP address for the pi it said 500 internal server error.
I did check these pages as I had the same problem previously on a Raspbian install and have made sure that power requirements for pizero are met and the SD card is completely fine (zeroed sd card and checked read and write across entire card no bad sectors)
I'm completely stumped! It seems to do something to the whole system as I am unable to even SSH in when this error presents. I had to remove power and then reconnect power. Pihole was up then for approx 24hrs and then the same again.
I don't have any logs and I'm not sure why - I've checked the SD card but logs folder is empty
Details about my system: Pi Zero (w) running headless with dietpi installed system monitoring is all stable. Using latest pihole (from install script on website) and unbound.
What I have changed since installing Pi-hole: Pihole is DHCP server and also using for all devices on home network as DNS Server
I would appreciate any help as currently pretty unusable and I love this project when it was working!
