Cisco AP won't connect to Controller. Need help!!

[miwotka]

There seems to be some kind of issue going on with the WLC (Cisco 5800 series) my organization uses. I am unable to configure new APs and the current APS are all disassociating from it. Any idea what's going on here???

@miwotka hello, check is the date and time in controller is correct. if its correct share the console output from failing AP

In addition what requested before.

Hope all the AP are working before and recently all AP disconnecting right ?

what code running on WLC, what Models of AP these are ?  connect console to one of the AP and post complete boot log until it fails.

Also check troubleshooting guide :
