Hi this code indicates a connection error, make sure all connections are tight and pushed in fully, particularly the white coxial cables to the box & hub and the hub is in an upright position, how is your hub connected to the V6 with a Ethernet cable or WiFi, Ethernet is the most stable and efficient connection.Regards Micky
This is usually the result of a poor connection tothe hub from one or both boxes. Are you using WiFi to connect them to your network? This is the most vulnerable to issues due to contention with neighbours hubs. Also the 2.4Ghz band can be too slow to make a good enough connection for streaming.
On the affected V6 go to Home>Help & Settings>Help>Our other Products>Broadband>Take a Speed Test.
At the speed test start screen press PLAY (not OK). This will give you an idea of your Download/Upload speed over your home network.
