Today I had the same problem with another AP, the wlc version is 17.3.3 (recomended).

If Someone know how to solve it, I would really appreciate it.

Hi,

is the time and timezone in WLC is correctly configured?

[balaji.bandi]

1. First i would check Physical connection, what logs you see where the AP connected ?

2. Maybe  BUG 

3. is this only AP having issues with all other AP, and is this first-time setup, working one broken?

Also please post the information below : 

- WLC:  sh sysinfo

- WLC:  sh time

- AP:  sh version

- AP:  sh ip interface brief

- AP:  sh inventory

Since you are running a Catalyst WLC, please post a Radio Active trace for the AP MAC address.

I would also like you to check and make sure that you have followed the deployment guide published by Cisco.

Pay attention to all the steps listed under “Configuring the 9800-CL via the CLI: Skipping the DAY 0 guided flow”

As Kasun mentioned  above make sure that the NTP is synced.
