First of all, sorry for my very bad english but I'm French.
I don't understand why, but for the past few weeks I must absolutely had to do a pihole -r to have Pihole re-scan all of my devices on the network, every 2 days.
If I don't, it displays 0 in the Clients windows that it analyzes, as soon as I do pihole -r everything is back to normal. My installation is only one month old, and the ONLY thing I have changed is updating raspbian ans Pihole.
Sudo apt update && sudo apt upgrade
This is absolutely everything I changed on my Raspberry PI3 B + which I only use for Pihole.
Can someone help me please?
Thank you in advance and see you soon.
