Photon shows connected but it doesn't work

Hello :slight_smile:

My photon was running for a while without a problem. Yesterday it suddendly stopped working (went offline from cloud). Because it’s in a remote area it’s difficult to access for me. I have received a video of my photon with a cyan status LED (I cannot determine if it’s breathing or just on without breathing , but I can clearly see that it’s NOT flashing). What could be the issue?

It has turned out the the photon has been freezed. After a reset it’s working again. What can I do to prevent an issue like this? Can I add a software watchdog?
