Can't connect to Mosquitto Broker

[email protected],

I’ve just moved to HA and absolutely love it. Now I’ve tried to setup the Mosquitto broker addon, and it seems to work but I can’t connect to the mosquito server from any other host but ha itself.

I’m able to publish message over the mqtt integration but when I try to connect to the broker with a client (e.g. mqtt explorer on my mac) I get “Disconnected from server”.

The logs aren’t helpful for me. What am I missing?

Here is my addon configuration:

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

And also the logs from mosquitto:

I’ve tried to reboot HA and also the whole host but that din’t fixed the problem.

I’m running Home Assistant OS with version core-2021.12.7 on a Raspberry PI.

I hope you can help me :worried:

Double check that the sockets are defined under Network on the Configuration tab of the add-on:

Network

Container Host Description
1883/tcp 1883 Normal MQTT
1884/tcp 1884 MQTT over WebSocket
8883/tcp 8883 Normal MQTT with SSL
8884/tcp 8884 MQTT over WebSocket with SSL

Thank you! It is definitely too late. I’ve been sitting on the configuration all day, I must have made a mistake while typing. Thanks a lot! :heart_eyes:

In my case I set the Normal MQTT Port to 1833 instead of 1883.
