I have a couple of photons deployed in the “wild” and after several months of proper operation, they lose connectivity to the cloud and my MQTT server. Most of the time, when this happens, I use Particle Workbench to re-upload the program, and things are working again. However, this last time, I get a message “Device is running debug firmware which does not support OTA. Reflash Device OS using Workbench or CLI (particle update)”. Per console, my device has 1.4.4 loaded.
