I need some help. new to pihole and very basic linux user here.
i setup Pihole 2-3 weeks ago. everything works as expected. Today i had outage and thought was my ISP. Finally able to isolate down to Pihole. Pihole device cant access or reach anything on the internet. tried both dns and IP addresses but able to reach my gateway.
router is RT-AX86U on merlin firmware. i disabled filtering and DNS to restore internet.
Pihole is runing on Centos 8
