"Could Not Sign In" on Apple TV

I am going nuts trying to figure out how to fix this. When I use my Apple TV for Netflix, Youtube, NHL, etc it all works just fine. When I try to rent a movie from Apple (iTunes) it has a black screen, the message "Could Not Sign In" and an okay button and that is it.

I have full connection to my WiFi according to the my network info in the General tab. The only answers I have found is to use a micro-HDMI cable but this appleTV doesn't have that. It only has an Ethernet, Optical, and HDMI ports. I have not tried to hard wire it as the TV is on the other side of the house from the router and that is how I want to use it.

Anyone have any ideas before I try to use this as a skipping stone across my pond?

Solution 1:

Use your Computer and log in in to iTunes with it.

Then just leave it logged in.

Now try again with your Apple TV.

Solution 2:

I had the same problem and it wasn't solved by resetting or restoring Apple TV from the box or via iTunes (after attaching the TV box to my computer). Turning box and/router on and off didn't work either. But I did solve the problem in the end. Download the Apple TV remote app from the App Store; follow the instructions in the app to connect your phone to your Apple TV as a remote; then sign in to iTunes via the phone app instead of the original remote (much easier anyway as you can type your Apple ID and password) and it lets you in. At least it did me. Phew, I can now access all my purchased content again. NB the app remote isn't the most intuitive thing - to move right, left, up, down just swipe on the blank bit of the screen above the menu button. Hope that helps folks.
