On certain ConnectKey in customer environments (and in some Xerox demo rooms), whey they open the QR Code app on the MFD LUI, they see the icon on the right, but the icon on the left does not load. Instead, they see, "Network Connection Error. Ensure that your device is connected to the network and that your network is properly configured." Any idea why they might get this error? Their device is on the network and it appears to be properly configured. I cannot recreate the problem.. See attached picture.
