"Could Not Communicate With Server" error on iCloud login with Apple TV Gen 3

The listed procedure that you quote, can still fail by an expired code, because it is taking too long.

I would suggest to first enter the password (do not submit yet), then request a code, add the code to the password, then submit.

Some reports indicate the allotted time is just 30 seconds from receiving the code. Adding six digits should be feasible in that time frame.

"If you follow the instructions precisely it will work unless you are entering information incorrectly.

This procedure works best for most:

1. From an iPhone or iPad, go into "Settings" => click on the top bar with your name and "Apple ID, iCloud, iTunes & App Store".
2. While still on iPhone or iPad, tap on "Password & Security", then tap on "Get Verification Code", LEAVE the supplied verification code visible.
3. Go to the iTunes login on your AppleTV settings and start logging in.
4. When it asks for your password, enter your password and add the verification code to the end of your password (no spaces: If your code is 123456 and your password is “ABC” you would enter “ABC123456”) BUT DO NOT HIT SUBMIT YET !!!
5. Go back to your iPhone/iPad and tap on "OK" on the verification code to make it go away.
6. Now go back to your AppleTV and submit the password."

I am getting this exact same problem. factory reset the appleTV, can log into iTunes on it but getting the "Unable to sign in; Could not communicate with the server" message. When I try a verification code it says the password is wrong. So no luck just like the original poster

If attempting to enter the password and code together as outlined above, then that will easily exceed the time limit. You need to enter the password, then request the code and then add the code to the password.

If you are following the steps provided by the other user above then as I said that will easily exceed the time limit. You need to make sure you are only entering the password first, then you need to be requesting the code, and then add it to the password. This will make sure the time is used exclusively for the code.

I am not sure what I was doing wrong the first time but I tried it again and it worked! Maybe it was because I was switching windows on my iphone as I was using it as my Apple TV remote so it timed out? Anyway I tapped OK after I initiated the verification code and then entered it in with my password and it worked. Thank you.

These steps worked perfectly. I read this method from another discussion, but couldn't get it to work. The fix for me was hitting OK on the other device and then clicking submit on the Apple TV. Thanks!

I’m having exactly the same problem!

I am following the steps above as well and still getting the “could not communicate with server” message?

All right, I admit it: when I did it really fast it worked.
