MQTT stoped working in HA

Configuration
1

I’m using a Raspberry Pi, with Hassbian OS , MQTT stoped and after searching, I think the solution is in some thing called snapshot, but unfortunately I don’t have it or what is it exactly, if any one know what to do ?

any sign of that?

source?

here’s a description, not sure that’ what will fix your MQTT though…

Are you using the mosquito mqtt addon? Did you recently upgrade to v4.1 of the addon?

If so you need to add an ACL. Mosquito update 4.1 - ACL messages in logs

I still find v4.1 a lot less stable than 4.0 was. I’m getting loss of contact between the broker and HA every few days of continuous up time.

The solution to loss of communication ( after adding an ACL) is just to restart HA. So it appears to be a problem with HA talking to the new version of the addon.

no addon with hassbian.

What does the mosquitto log say? What does the home-assistant log say? Is anything running on the mosquitto port?

sudo netstat -tanp|grep mosquitto
