I have an unknown IP pinging my broker every two minutes. Is this a known service I need to know about?
> 2022-09-10 06:45:32: New connection from 172.30.32.2:34706 on port 1883.
> 2022-09-10 06:45:32: Client closed its connection.

Hi walkerhunter,
I have not yet encountered this myself.
In what context are you using your mosquitto?

Hi @Tizian,
I use the mosquitto broker in a domestic environment, integrated to HomeAssistant with no special configurations. Considering that the connection requests keep coming and from the same IP address I am starting to wonder if there is a misconfigured device on my internal LAN.

Hi walkerhunter,
I guess if you are using home assistant, this could be the reason 🙂
