iPhone X won't connect to home wifi, says incorrect password when password is correct

Hi all. Out of nowhere my iPhone 10 suddenly can't connect to either of my home wifi networks. All other devices (iPhone 6, MacBook, Echo Dot etc) are connected and the wifi passwords have not changed.

The error msg I continue to get is INCORRECT PASSWORD for network and then it lists the name of the network. This is incredibly frustrating and I've tried all the "fixes" suggested online. Anybody have any ideas? Yes I have tried the password for both networks about 30 times and made sure I was typing in the correct letters.

No clue what the problem is this literally happened out of nowhere this afternoon. I even tried RESET NETWORK SETTINGS which did not work. I also updated to iOS 11.2.6 thinking that could be part of the problem but I still can't connect after the update.

I have AT&T cellular service and Comcast Infinity WiFi. I have not had a chance to take my phone elsewhere to test on other wifi networks as its almost 11pm PST

Any ideas? Thank you so much
