[BUG] MQTT connection lost

[elgutierrez]

Describe the bug
I have a gateway that's working fine for a while, and then, all the sudden, it can't connect to Thingsboard anymore. I already checked the network configurations and Thingsboard Cloud is reachable from my device.

Error traceback:

Hey, can I get some feedback here? I have some devices that start failing pretty much every day and at the end it requires a manual reset to be able work properly.
