Lynx Shunt Disappeared from CAN

I have a Lynx Shunt that has been in service for almost 4 years. It is no longer showing up and of course my DC Load shows 0. I have two more CAN devices, 250/85 MPPT’s, that are after the Shunt in the CAN chain that are showing up. I have a green power light on the Lynx Shunt, but it no longer shows up in devices. Has the shunt it self died inside?

While poking around my CAN device I found an item from Victron that I can’t identify. It is listed as System Battery.
