Suddenly mqtt 1883 port in use error

Configuration
1

Hi

I have hass.io installed on standalone intel nuc running ubuntu desktop. Has been working fine using mqtt hass.io addon broker. Suddenly the mqtt hass.io is no longer working and gives the following error:

1541444743: Opening ipv4 listen socket on port 1883.
1541444743: Error: Address in use

I have not changed anything in my setup, just overnight it decided to stop working.

This is my configuration for mqtt broker addon:

{
  "logins": [
    {
      "username": "mike",
      "password": "xxxxxxxxx"
    }
  ],
  "anonymous": false,
  "customize": {
    "active": true,
    "folder": "mosquitto"
  },
  "certfile": "fullchain.pem",
  "keyfile": "privkey.pem",
  "plain": false,
  "plain_websockets": false,
  "ssl": true,
  "ssl_websockets": false
}

and

Container : Host
1883/tcp	 : 1883
1884/tcp	 : 1884
8883/tcp	 : 8883
8884/tcp	 : 8884

This is my configuration.yaml

mqtt:
  broker: 192.168.1.50
  username: !secret mqtt_login
  password: !secret mqtt_password
  discovery: true
  birth_message:
    topic: 'hass/status'
    payload: 'online'
  will_message:
    topic: 'hass/status'
    payload: 'offline'

If i use ssh and type “lsof -i TCP:1883” i get the following output

root@nuc-server:~#  lsof -i TCP:1883
COMMAND    PID USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME

Can anyone tell me what I can do to get it going?

I have tried the following command:

root@nuc-server:~# sudo systemctl stop mosquitto.service
Failed to stop mosquitto.service: Unit mosquitto.service not loaded.
root@nuc-server:~# systemctl status mosquitto.service
Unit mosquitto.service could not be found.

ok i have the solution.

step #1 - remove mqtt: and everything under it from configuration.yaml , you don’t want mqtt and you don’t want any of the mqtt config entries in configuration.yaml

step #2 - goto hass.io -> mqtt add on config page. click reset to defaults.

step #3 - restart home assistant

step #4 - goto configuration -> integrations -> mqtt setup -> open the dialog box and setup the mqtt component.

step #5 - restart home assistant again.
