Been running this switch and a EAP 620 for months no issues then all sudden today I try to access the controller through the app on my phone and both devices have adoption failures.  When I got home to actually log in to the computer and the devices it claims the user and passwords are different on the devices so the controler can not adopt them.  I havent changed anything since initial setup.  I have attempted to re-adopt with the user and password for my cloud access and the user and password in the controller neither work.  Any ideas? The Eap620 is saying that it is not responding to adopt commands
