Every month or so all my devices lose internet and the only way to connect them all back is to disconnect them from the DNS server that Pihole is running.
I set my Pihole to have a static IP but for some reason after around a month or maybe longer, it just fails. This has happened 4 times over the last while and the only fix is to essentially uninstall everything on my Pihole, disable it, and then reconfigure it from scratch again.
I’m not sure what’s going on so any help would be appreciated.
I have a google router and It allows me to enter 2 DNS servers incase the first DNS Server doesnt work.
That's pretty standard for nearly every router and Internet connected device. There is almost always a setting for Primary and Secondary DNS servers. Sometimes you can even set more (ie. 2 IPv6 DNS servers in addition to the 2 IPv4 DNS servers)
