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.
Do you run your PiHole on top of Docker? There's an issue with docker and Raspberry Pis which makes the network crap out periodically. So if your PuHole becomes unavailable until you restart your Pi it might be this:

Solution is to add "denyinterfaces veth*" to the dhcpd.conf
Oh my gosh. I have been trying to figure this issue out with my docker containers for months. If this is the fix, THANK YOU.
I have had this issue for about a year, while trying different monitoring and logging solutions to try and find out what's going on.
This was such a bitch! Now I'm spreading the word, so that other won't suffer as long as I have.
PuHole 🤣
Hahaha! I'm keeping this typo 😂
