> I have a flow that is running a ConsumeMQTT processor, successfully connected to the MQTT broker and consuming data. When the agent is restarted the following error is shown on the minifi-app.log:
> {code:java}
> [2022-06-25 12:19:04.189] [org::apache::nifi::minifi::processors::AbstractMQTTProcessor] [error] Failed to subscribe to MQTT topic iot/# (-1)
> {code}
> The ConsumeMQTT processor never recovers from this error.
> After this, if I restart the agent, the ConsumerMQTT processor will manage to reconnect to the broker successfully and start consuming.
> If I restart the agent one more time, the cycle above repeats.
