MQTT integration - stopped

1

I have been using HA and MQTT for a couple of years without problems. Last week the MQTT integration have stopped working and I’m not getting data nor can I send MQTT from HA.

Mosquitto broker is running fine and I can see messages using mqtt-explorer
The log shows endless amounts of wierds connection:
2024-07-31 13:33:02: New connection from 172.30.32.2:59262 on port 1883.
2024-07-31 13:33:02: Client closed its connection.

HA usses enp0s3: 192.168.0.xxxx

eth0 is 172.30.33.2 - Which seems wrong and perhaps the MQTT integration is transmitting on the wrong ip address because a restart gave this:

[13:47:23] INFO: Successfully send discovery information to Home Assistant.
[13:47:24] INFO: Successfully send service information to the Supervisor.
2024-07-31 13:47:45: New connection from 192.168.0.200:33588 on port 1883.
2024-07-31 13:47:45: New client connected from 192.168.0.200:33588 as nodered_1473296315633694 (p2, c1, k60, u’xxxx’).
2024-07-31 13:48:26: New connection from 172.30.32.1:45771 on port 1883.
2024-07-31 13:48:26: New client connected from 172.30.32.1:45771 as 5fja3EecTaUr4tqZmLhZZD (p2, c1, k60, u’xxxx’).

And then the rest is from 172.30.32.1:45771

Any ideas for solutions or how to troubleshoot this?
Thanks

That is the the Supervisor watchdog checking to see if the mqtt broker is ok.

If you want to test this, turn this off and the messages should stop:

Also 172.30.33.0/24 is the internal docker network.

Thanks, that cleared some noise.
I’m not running docker, HA in VM on an old Windows Labtop.

Unless you are running core (you are not, you have addons) you have Docker containers. Supervised and HA OS installs also use Docker containers.

Home assistant core is in a container, the supervisor is in a container, add-ons are containers.
