Apple TV won’t let me enter WiFi password - error code (-100)

My Apple TV suddenly disconnected from my WiFi and won’t reconnect.

when I select my network name from the list, I don’t get the chance to enter a password - I get “the WiFi password you entered is not correct. Try again. (-100)”. I can select other networks and go to the password entry page; just not mine.

I’ve read other posts about the password or network changing, but this hasn’t been the case for mine.

What is your model Apple TV?

What is its version system software?

Try the steps as mentioned in: If your Apple TV can't connect to Wi-Fi - Apple Support
Try the ‘Other…’ option instead of selecting a listed discovered network. Especially if the password has been changed. This would require to type in both the network name and the password.
For Apple TV (4th generation or earlier), verify that the router or access point isn’t set to use WPA3, as only device models from ~2018 or later support that. Instead use ‘WPA2/WPA3 Transitional’. Some users report that they had to set ‘WPA2’-only first.
