Stop shutting down the device resource in MQTT

Hey there, I have connected NodeMCU to Thinger using MQTT protocol. But after a while, Thinger automatically shuts down the device. I am implementing temperature analysis system where in I am sending data from temperature to thinger bucket every 15 minutes. How do I stop thinger from shutting down devices? Here are some logs of the same. Thanks in advance. :slight_smile:
