"Apple TV cannot connect to server at this time"


Try to unplug the Ethernet cable and wait for 20 seconds then plug it back again. You can also try to unplug your ATV3. If those two methods do not work, you can reset your modem, and resetting on the Apple TV. Last method is to press the menu button for 6-7 seconds which should help solve the problem. Let me know if any of the solutions help.
