Ring Doorbell won't connect to wifi

I have two Ring Video Doorbells, original version. After a long period of use, one of the units disconnected from wifi. The error message is that the wifi password is incorrect. I have tried several networks and created a separate network for the Ring devices. I have also hard reset the device several times. Any ideas on how to fix this? Thanks!
