Android tablets saying Wifi password incorrect, but working on other devices

[jacstesi85113]

At my parent’s house, all of my devices have used WiFi here before. My iPhone and iPad both automatically reconnected to the WiFi here, but my two android tablets (Galaxy S6 Lite and Alcatel) did not reconnect and when I type in the password it says incorrect. My dad double checked and confirmed that it is in fact the right password.

Already tried:
Restarting devices
Reset network connections on Galaxy tablet
Turned Airplane mode on and off
Did the “forget device” and then tried connecting again
