"lost CAN connection to other module" error


I'm using the 1290 Infinity II LC System and I've had this error "lost CAN connection to other module" show up in my last two injections. Has anyone seen this before?

I've checked all my connections and cables and nothing seems to be wrong. After clearing the error I'll re-start the instrument and it seems to work the way it should until I start my injections. The first time it happened at the beginning of the run but this last time, it occurred halfway through my sample set. 

Does anyone know how I can trouble shoot this?
