<p>Are you connecting to the backend via a static ip address, hostname or on the loopback (127.0.0.1). Loopback should work but if your network connection dies to the pc the network card setup loses its ip address cause the network card could think the cable is disconnected. It depends on the type of failure you are seeing?</p>
