Ring Video doorbell wifi setup

I have had a video doorbell set up for a few months now. It has worked fine, however this morning at 10:30 it stopped sending notifications to my phone app and allow showing it was online would not work. I have tried to reset the device through the app and gone through the wifi set up procedure, however the device will not connect to my phone when i try to connect to the Ring Setup e4 Network which comes up on my phone wifi search. It gives a can not authenticate connection message after trying to connect.
