Ehlo,
I installed mosquitto on an Ubuntu 16.04 variant (elementary OS) and set it up with the following configuration :
allow_anonymous false
password_file /etc/mosquitto/passwd
listener 1883
listener 8883
certfile /etc/letsencrypt/live/example.com/cert.pem
cafile /etc/letsencrypt/live/example.com/chain.pem
keyfile /etc/letsencrypt/live/example.com/privkey.pem
My MQTT configuration in HA is :
broker: example.com
port: 8883
username: hass
password: !secret password
protocol: 3.1.1
I use owntracks and several Sonoff Tasmota Wifi switches with that broker. Using an MQTT client everything works flawlessly.
The problem is that MQTT doesn’t work in HA but no errors are shown in the logs. Publishing from HA to MQTT doesn’t work. Here is all I have in the logs :
cat /var/log/home-assistant.log | grep mqtt

Does anyone have an idea to help me debug this ? Thanks in advance for the awesome software and community.
