Please start menuconfig tool and double check (sub-menu ThingsBoard OTA configuration) that the correct values were specified for:

• MQTT broker URL
• MQTT broker port
• MQTT access token

Hey I'm getting the same issue while running the app.

What is the correct broker URL and port for thingsboard cloud?

I am currently using
MQTT broker URL = mqtt://cloud.thingsboard.io
MQTT broker port = 1883
MQTT access token = access token for a device ive added on thingsboard.cloud

Thanks.
