Like most have said the issue was with the time, the ap can only sync with the controller if the date,time and country configured is the same on both ends.

Im moving from controller A to Controller B with the same version of software and any of the APs join to my new controller. Im getting the same debug outputs than this original POST.
I have to clear the prive config too?

El problema del post Original es que tiene incorrecta la fecha del WLC. En tu caso la fecha es correcta? tu nuevo WLC esta en el mismo segmento de red que el original?

DTLS connection may fail due to expired license, check "show license all" and if you find license expired, go to Management-- software activation-- License and add new license.

Hi Cisco Team,
We have almost the same issue but it happens when we fail over the link from ISP 1 to ISP 2. The AP cannot join to WLC but from WLC side I can ping the access point. Please help us guys. Thanks
