@inger Well we really need to isolate just the fog server and target computer on the same network switch. Right now we don’t know where the problem is. It sounds like a network issue. I assume both the fog server and target computer nics are in working order, so we need to look at what is in between. So my recommendation is to start small and see if it works. If yes then start expanding the scope of devices.
At this point I don’t think its the fog server at fault, but something in the infrastructure. I’m not trying to point blame some place other than fog, it just seems like an intermittent network issue.
