P2 with Device OS 6.2.1 dropping cloud connection

I left a P2 with a Log to serial monitor and came back to it with the LED breathing white (restarted and was waiting to have serial available conformed) and this on the log:

Does this give any explanation as to why it disconnected and could not reconnect?

The device shouldn't go into breathing while unless it was manually put into network off mode. If it failed to connect, it would be blinking green or cyan continuously; it does not go into breathing white no matter how long it fails to connect.

I think if you do not have Wi-Fi credentials and have disabled listening mode (because you are using BLE provisioning mode) you might go into breathing white, but since you were subsequently able to connect that probably wasn't the issue.

It had reset and was breathing white waiting for a serial connection. My question was about why it had dropped the cloud connection?
