Connection not authorized from ioBroker MQTT Client

Hello everybody,

I have subscribed for the free HiveMQ cloud and now trying to make a connection to it from my ioBroker home automation platform. There is a plugin called MQTT Client (on github) with a small set of settings. I’ve tried out every combination of ports, with and without SSL but nothing works. I always get connection refused. Has someone else established a connection with ioBroker?

Hey Alex,

I do not have any experience with ioBroker’s mqtt client plugin. Are you generally able to connect to your HiveMQ Cloud instance with other clients? For testing purposes I highly recommend HiveMQ’s MQTT CLI.

Kind regards

Hi @zingiber,

sorry I didn’t get a notice of your reply. I’ve tried to establish a connection from Python from the same server and this works. The problem is, that the ioBroker plugin does not log any further data for the connection error.
