I can't figure out if it is 192.168.1.147 connecting to my broker or if my broker is trying to connect to it?
I greped for "inform" in all the code but didn't find anything - which makes me think it'd be outside trying to access me... but then:
it doesn't stop, even if I switch ports, which makes me think it must be the program or somehow it's scanning everything.. idk

Also the IP seems to be my ubiquiti access point, which might have MQTT I have no idea, however not sure why it'd go after my computer.

So is it the AP trying to access me for some reason?
