WLC 5520 AP's not getting registered

[zumriatha]

HI guys,

I got a 5520 Wireless LAN Controller with 8.3.143.0

trying to connect AIR-AP2802I-K9 with running image 8.5.140.0

just to let you know I have connected them on a local switch on a testing environment as im using this for a bigger project im very new to this subject so i would appreciate your support..

My management interface 192.168.60.2 which is on native vlan 60

and i have connected a DHCP server on the same vlan (192.168.60.25)

to keep it simple i have connected the AP also in the same VLAN

I keep getting this message on the AP cant find the ip from discoveryRequest array

and the following

WLC's time and date could be wrong.  

Make sure NTP is synchronize.

 - Check compatibility notes for AP and controller software from link below , also add the time of problematic joins issue the command show logging on the controller, watch for error messages if any :
