Cannot sign-in to iCloud on Apple TV: Could not communicate with server
I receive an error message when trying to sign in to iCloud on my older Apple TV device (3rd gen, I believe). It has a strong signal, and all the apps, etc. are working properly. I can sign into iCloud on all my other devices. This happened before I installed the recent update, and the message is the same even after the update. Can anyone help?
The message says:
