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