Q: I'm trying to use Apple TV, but I'm receiving a message that My ID is not right. I tryed serveral times, I'm sure my ID and password are right. Suggestion, pls?

I am having the exact same issue. it is suggesting that I am getting my password incorrect.

If you have an iPhone, try this workaround.

1. Setup Personal Hotspot on your iPhone: Share your Internet connection with Personal Hotspot - Apple Support

(If you don't have an iPhone, check if your phone allows to Share Internet with other devices, if yes, then look in your phone manual how to turn on this option)

2. Temporarily connect your Apple TV to Personal Hotspot connection created from your iPhone.

3. Sign in to iTunes Store with your Apple ID.

4. Reconnect your Apple TV to your home Wifi: Get help with Wi-Fi networks and Apple TV - Apple Support

If that setup worked, call your ISP and asked them to unlock for you ports listed in this article:

If your Apple TV stops at the date and time screen during startup - Apple Support

TCP and UDP ports and protocols used by Apple TV - Apple Support

Happy I could help.
