The issue is the mqtt library seems to have connection handling isssues. While trying to connect to MQTT I get ECONNRESET.

What are the steps to reproduce this issue?

Placing this file under /lib
Use Lopy4
Try to publish a message to an MQTT broker based on this tutorial

What happens?

You will receive this error:

Traceback (most recent call last): File "", line 26, in File "/flash/lib/mqtt.py", line 223, in connect OSError: [Errno 104] ECONNRESET

What it was expecting to happen?

Connect and publish message to MQTT
