Thanks Ivan - one of each,Wifi and Ethernet. Have tried them on the other, no joy. It looks like some sort of issue with connecting to Vodafone.
You didn't by any chance make the mistake reseting them when asked to during the recent gloabl Vodafond outage of Vodafone TV. If so then I suggest removing them from the VTV online devices and restarting which should if Vodafone still supports it register them as a new device. By the way you may need to do this on ethernet connection rather than WiFi.
