I'm getting this over and over on my log.
I have my windows PC and Raspberry pi as wired devices. all else is wireless.
RPi is running pihole with PiVpn on Wireguard.
Router's DHCP is disabled, I'm using Pihole's DHCP.
I'm also using Cloudflared DoH.

That's the gist of it.
But this log spam is a new thing. Would love to know what to do with it.
