hello everyone, since i'm having exactly the same issue
(pihole installed on raspberry pi if i get power outrage , when RPI reboot , pihole won't work and i can't access internet until i access to pihole ip 192.168.1.10 on web and restart dns resolver in settings)
i was wondering if this is the solution to this problem!!
1/ I installed ntp on the Pi.
2/ I forced "nameserver 8.8.8.8" on /etc/resolv.conf
3/ I change the right of this file to 555 to avoid system modification each time.
my pihole works as dhcp server and dns so Alexa, and any other device/pc at home won't work until i restart dns resolver manually !
thank you
Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:
actually tonight I just had a powercut so it should be visible
(yesterday instead I made some tests so that happened quite often) https://tricorder.pi-hole.net/4sUqB56p/
thank you
