Cannot connect Apple TV to iTunes Store

If two-factor authentication isn’t the issue, then possibly something about the internet connection or your account is preventing connecting to the Store.

For the internet connection: Try restarting both your router and Apple TV box, then try again.

For the account: Try on a different device (e.g. iPhone), if you have that available. Else contact the Support staff, to ask if they can see anything off about your account.

Not sure what the model is

That is why the link to the support document was included, to help identify which one.

If your Apple TV box is 0.9 inch (2.3 cm) in height, then you have a 2nd or 3rd generation model.

If your Apple TV box is 1.4 inch (3.6 cm) in height, then you have a 4th generation or later model.

If you have an Apple TV (2nd or 3rd generation) and two-factor authentication for your Apple ID, then you may be asked to type your password followed by the six-digit verification code directly into the password field. Additionally, there is a time limit, after which the code becomes invalid.

Try this: First enter the characters of your password (do not submit yet), then manually request a new verification code, then append that code to the password (no spaces or other separating characters), and then submit. That should help you get passed the time limit.

If your have an Apple TV (4th generation or later), then the above doesn’t apply.
