WCS4402 not authenticating 802.1x

Our Cisco WCS4402 suddenly stopped authenticating 802.1x clients.  Public WLAN works fine.  Software version 4-1-185.  Sytem has been rebooted several times.  Any suggestions appreciated.

Hi Dave  No recent changes?  I would first check the wlc log and post what it reports on one of the failing clients  On the acs side.. Look under the failure log and see if you see an error MSG for this client post what you see

Hmmm nothing changed?

As your code is quite old I would check the cert validity on the RADIUS side,

Definitely check the logs if you are using Windows or ACS the logs give pretty straightforward error messages that will help.
