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 had similar issues when SLAAC wasn’t properly configured for my network. Every however many days my ISP forced a modem reboot and if the delegated prefix happened to change I’d start having pihole problems. I finally tracked that down, made sure SLAAC was working everywhere and assigned my pihole container a SLAAC token so its address relative to everything else on the network didn’t change and I’m good to go. These days the pihole is always …253 and ::253.
