Error in connection to MQTT server

1

I am using the MQTT CLI and get this error no matter what command I use… any troubleshooting suggestions… I have the mosquito server running and the config file looks OK. Seems the connection is refused.

Traceback (most recent call last):

Hey Jerryyyyyyyy

Let’s start by making sure you got mosquito set up properly

Here’s my config:

logins: []
require_certificate: false
certfile: fullchain.pem
keyfile: privkey.pem
customize:
  active: false
  folder: mosquitto

and here’s my mqtt user

and here’s the mosquito configuration but from my insteon-mqtt config.yaml:

#==========================================================================
#
# MQTT configuration
#
#==========================================================================
mqtt:
  broker: core-mosquitto
  port: 1883
  # Optional broker login data.
  username: mqttuser
  password: **********

obviously your password should match the one that you created for the user. the docs clearly state that you should NOT use the homeassistant user.

Hi,
Slow getting back…
My configuration in /config/insteon-mqtt/config.yaml is not the same… actually looks empty.
I made a mqttuser… now I better go back to wherever the mosquito thing was set up… so I did not see how to change the settings, I uninstalled it, reinstalled and then it gave me the error :

Failed to save add-on configuration, Unknown error, see supervisor logs

So then in the logs:

Disconnected from MQTT server 192.168.0.164:1883 (7)

4:27:30 PM – (WARNING) MQTT - message first occurred at 4:23:23 PM and shows up 3 times

/addons/core_mosquitto/restart return code 500

Maybe better see if I can restart HA and try again… about to give up here… I have updated the system and there seems to be a new set of options for Insteon…

After restar the log:

Hopefully folks with mosquitto knowledge can help out here. “Mine just worked” is not a helpful response… sorry.

There’s an open bug report for this at Mosquitto broker Add-on is not initialized correctly when HA starts · Issue #2618 · home-assistant/addons · GitHub.
