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 run pihole on a proxmox cluster (lxc containers), 2 separate IPs and I setup keepalived and made the virtual IP the primary dns ip that my dhcp server hands out, pihole1 is the master and pihole2 secondary. I use gravity sync to keep both piholes in sync. Works very well and I can reboot one at a time without losing dns at all. Techno tim on YouTube has a guide on how to setup keepalived on 2 pihole servers that helped me set it up.
