Please change mqtt:// to tcp://.

$ docker run --rm inovex/mqtt-stresser -broker tcp://broker.emqx.io:1883 -num-clients 1 -num-messages 10 -rampup-delay 1s -rampup-size 10 -global-timeout 180s -timeout 20s

@hikhvar I am not aware of mqtt://, maybe we should dig into latest MQTT development and also verify MQTT5 support.

[Christoph Petrausch]

I think we do not support MQTT5 at the moment. The MQTT client needs an update.
