No lights on radio 3 controller

Rachio 3 controller setup one month ago, been working great
Model 8ZULWC Serial # AC2844755
V Got up two days ago found controller with no blue light on . App indicated not connected to wifi. Tried disconnecting power supply for 15 seconds and longer plugged back in still no lights.
Pressed wifi button on controller nothing happened
Tried removing controller from app, the app could not recconnect to controller. Tried resetting wifi the wifi works fine but cannot see the controller
Downloaded Routethis app and ran test the key is DMT8MASX

Put voltage meter on power supply has 26 volts
What can I do is there any other way to reset

@Jay1 - I’d submit a ticket to IMHO, sounds like an infant mortality on the controller.
