There is a new firmware update available for the Apple TV 4K. When I attempt to update the firmware, I get an Unable to Update at this time error.
Restarted the Apple TV several times. Checked the network connection. Still unable to update.
I have not yet disconnected my Mediacom Cable Modem so I moved the ethernet cable from the T-Mobile Gateway to the Cable Modem. Restarted the Apple TV and attempted update. Firmware download immediately began.
So why can’t the Apple TV download firmware when connected to T-Mobile Internet?
