Hi,
Expected Behaviour:
I'm running Pihole on a Raspberry Pi Zero 2 W, with Raspbian Bookworm. I've been using Pihole for years without issues. But for a couple of months now, presumable after updating to v6, the issue started to occur.
Actual Behaviour:
The Raspberry Pi on which Pihole runs completely looses network connection every couple of days, and I'm forced to reboot it. I'm assuming the Raspberry Pi is still running but I have no way to check as it is a headless server and I also cannot establish SSH connection anymore. I see these errors in the FTL.log file.

I've changed my configuration with suggestsion from a couple of help threads here without success.
This one UDP Error, among others.
I recently upgraded to Bookworm hoping it would somehow magically resolve the issue but that hasn't happened.

I would love some help with this issue.
