Hi,
i run MQTT / Mosquitto on a 192. Subnet. Those 172. messages are spamming my log. I would like to get rid of them.
I read forum posts from 2018, but they were not really a help to identify and get rif of the messages. Mosquitto watchdog is NOT running.

I run HA on Proxmox with:

Home Assistant OS Core 2025.11.2
Supervisor2025.11.2
Operating System 16.3
Frontend 20251105.0

Those are the messages.
