[info] [mqtt-broker:chirpstack] Connection failed to broker: df159228-918c-44b7-9338-588231047d21@mqtt://localhost:1883

i need your help please!
I got the following error when running this command “docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red”, to run nodred in docker.

I would like to know what is the problem please? How can I solve it?

It looks like NodeRED can’t connect to your MQTT broker. That is at least what the error is telling you :slight_smile: The solution is to make sure you put the correct hostname in your configuration for the MQTT broker.
