I can tell you what causes this. Loss of internet connection after an extended time online. Anyone with a VeraSecure can duplicate the problem by unpluging the network cable. In your case, your Vera is not acknowledging a network connection.
I got my VeraSecure because of the built in battery in case of a power failure to keep my alarm system online. Wow, what a wast of money. Power goes out, internet off, and Vera goes into la-la land. Not a problem with VeraPlus or VeraEdge.
BTW, loose the reset tool and unplug the battery. That way, all you need to do is unplug it to reset it to do a power reset.
