I dont any debug traces in the active flows:  
but mqtt is "ok" :  
[mqtt-broker:DRAGINO SENSORS] Connected to broker: mqtts://eu1.cloud.thethings.network:8883  
mqtt module is connect bat never module activates debug trace, may be a reason?  
Nodered is on raspberry

Have you subscribed to a topic that something is publishing too?

Install MQTTExplorer on your PC and connect to the broker with that to check what topics are being subscribed to.

The topic is missing  
Look at the guide because you must have the right topic to access your device (because TTN is public)

If you go to the TTN console, do you see that your device is active?  
Have you configured the topic as described in the guide?

> [@bpi2008](#):

> mosquitto version 2.0.11

Not useful, you connect to the public broker
