No connection from MQTT client

Hello together,

openremote installed Windows11/Docker as follows (changed Port to 1886)

Then I followed the steps exactly the way they have been mentioned here:


Service User

With MQTT Explorer configuration

i cannot connect on the local network. Error “Disconnected from server”

The attempt from a Raspberry with zigbee2mqtt brings 2 messages

Connecting to MQTT server at mqtt://192.168…:1886
Using MQTT login with username: master:mqttuser

and then aborts after about 30 seconds.

I am grateful for any help!

Hi Udo,

Just two things that I noticed: could you try without TLS and with port 1883?

Hello, I used this guide Notion – The all-in-one workspace for your notes, tasks, wikis, and databases. and it works
validate certif - off, encrypt - on
port 8883
