[homeassistant.components.mqtt] Failed to connect due to exception: [Errno 111] Connection refused


I install mosquitto because I want to use mqtt with shelly. I think I have a problem.
In the log I read [homeassistant.components.mqtt] Failed to connect due to exception: [Errno 111] Connection refused . I found in the forum that can be if the username or password is incorrect but I check several times.
This is the part in my configuration.yaml

  port: 1883
  client_id: home-assistant-1
  username: !secret mqtt_user
  password: !secret mqtt_pass
  discovery: true

This is the service status:

pi@raspberrypi:/home/homeassistant/.homeassistant $ sudo /etc/init.d/mosquitto status

Can someone help me?

Thank you.


I try to use also the mqtt home assistant integrated service, I have no error, but the system don’t work. I don’t receive the state of the cover and if I click the command the cover don’t receive the command.

Thank you.

Hi to everyone,
finnaly today I solve something.
If I use this command:
mosquitto -d
in the raspberry I’m able to command the relay.
But I have some problem:

  1. every time that I reboot my raspberry if I don’t use the command mosquitto -d I’m not able to command shelly.
  2. the state is always unknow. Is trange because if I use the sub command of mosquitto in the channelthere is a transmission of information:
    Client mosqsub/11824-raspberry sending CONNECT
    Client mosqsub/11824-raspberry received CONNACK
    Client mosqsub/11824-raspberry sending SUBSCRIBE (Mid: 1, Topic: shellies/shellyswitch-55C520/roller/0, QoS: 0)
    Client mosqsub/11824-raspberry received SUBACK
    Subscribed (mid: 1): 0
    Client mosqsub/11824-raspberry received PUBLISH (d0, q0, r0, m0, ‘shellies/shellyswitch-55C520/roller/0’, … (4 bytes))

Any suggestion?

Thank you

Hi, I upgraded to 0.99.2 today and HA could no longer connect to Mosquitto. All my MQTT sensors stopped working. I never had this problem before. When I used the command mosquitto -d as suggested in your post, HA was able to connect to Mosquitto/MQTT again and all are working now.
What’s the explanation for this?

I have the same problem with mqtt broker, means: connectio refused.

[core-ssh solarman]$ mosquitto_pub -h -t homeassistant/switch/1/on -m "Switch is ON" 
Connection error: Connection Refused: not authorised.
Error: The connection was refused.

my mqtt broker is working well, config is:

active: true
folder: mosquitto
anonymous: true
  active: true
  folder: mosquitto
certfile: fullchain.pem
keyfile: privkey.pem
require_certificate: false

My HA IP is

If using the add-on, that does no longer work.
