Trying to connect a freshly restored Apple TV 3 (MC572LL/A) (A1378) (TVOS 6.2.1 build 6698.99.50.41) to my iPhone 12 (iOS 15.2) Hotspot, but keep getting the message "The Wifi password you entered is not correct. Try again (-100)".
Problem is, I did not get prompted to enter a password, and I cannot find a way to correct this problem. And the iPhone Hotspot cannot be set up without a password...
Please advise.
Try connecting by using the Other option, instead of selecting a listed network.
Then enter both the SSID network name and its password.
Also set the iPhone hotspot to use the Maximize Compatibility option.

Thanks for the suggestions, but neither makes any difference. I still get an -100 error before getting a chance to enter the wifi password.
I am able to connect successfully to an iPhone 7 running iOS 14.8.1, so this feels like a bug in newer iPhones or iOS15.
Is that other iPhone using the same mobile provider and plan?
Please try the iPhone forum for more expertise on using hotspot with iPhone 12/iOS 15.
If you are successfully connecting to a different hotspot, then the issue seems likely with something about this hotspot, not the Apple TV box.
(A1378 is an Apple TV version 2, of course ;-)
I get an Error message (-100) on appletv?
