im using MQTT Explorer. everything seems to be working fine a month ago. BUT after adding a device, i am seeing constant disconnect as seen here. can a device do that??? or maybe just coincidence. all of my MQTT devices, including the new ones, are working fine (i think)
The usual question is about the regular Client <unknown> closed its connection. entries in the Mosquitto Add-On log.
I’ve no idea what could be disconnecting MQTT Explorer as it has been so reliable for me.
Have you tried pinging the server from the client and looking for lost network packets?
(i.e. is this something like a bad network cable on the client)
