Domoticz

I can not connect in MQTT Explorer with mij Rasberry ip adres where MQTT is installed.

Also i can not connect with localhost port 1883

It gives also problems in zwave-js-ui
2023-03-22 10:13:15.177 INFO MQTT: MQTT client reconnecting
2023-03-22 10:13:15.181 ERROR MQTT: Mqtt client error connect ECONNREFUSED 127.0.0.1:1883

In domoticz i have also Node-red with MQTT and thats ok. It works fine.
For node-red i setup in Domoticz MQTT with lan interface localhost en port 1883.

Dont understand why i can not connect in MQTT Explorer

Perhaps use the IP-address of the Raspberry instead of 127.0.0.1

Is not working.

What is in the logging of mosquitto?
If you put "log_type debug" in the mosquitto configuration, you will be able to find the cause.

The problem has been solved.

So what was the solution?

From Mosquitto 2 and higher its only possible to login with localhost on that device.
For another device you have to change some settings in mosquitto.conf. you can login than with raspberry ip
