MQTT connection resets

[zachjacobs]

Hello, I am having an issue running the esp32-ota example on a base install of Thingsboard PE. The ESP32 has the following error. I'm using ESP-IDF v3.2.3.

I (83925) MQTT_CLIENT: Sending MQTT CONNECT message, type: 1, id: 0000
I (84845) tb_ota: Connected to MQTT broker mqtt://****, on port 1883

And Thingsboard error version 2.4.1:
