Parent is disconnected, reason: 106

Environment

Development Kit: ESP32-DevKitC

Problem Description

I am working with a single node configuration and ESP-MDF.

The node, which is of course the root node, connects to wifi and gets an IP address. It also connects to a public MQTT broker and sends messages.

After a while, the mesh breaks and the board enters a loop as shown in the Figure herein attached.

Expected Behavior

I expect the mesh network does not crash. In particular, I expect that after the parent is disconnected, it is able to reconnect again.

Actual Behavior

After a while, the mesh breaks and the board enters a loop as shown in the Figure herein attached.

Code to reproduce this issue

The code I am using to manage the MESH events is hosted on GitHub, on the following page: https://github.com/lcarnevale/esp32-mesh/blob/main/main/include/events.h
