AP get IP from DHCP on WLC, its OK.
On the first power on of this AP, it joined with DHCP assigned address. I rename AP and change IP to static. After that AP not joined. In debug on WLC i not see any reasons.

[vivek NAGAR]

I think you are using STATIC , If you have console can you please check and share the logs which received.

and please verify the AP policies in security tab what enabled "MIC" or any authentication-LIST.

Thanks

WLC policy in attach

[vivek NAGAR]

Policy look good as it allowed "MIC" accept , do you have access for AP via console ? is DHCP is giving option 43 WLC information or you statically define WLC information in AP ?

[Dmitry Klimenko]

DHCP have minimum options in web interface. AP success get IP.

Log from console copy later...

[Leo Laohoo]

Is DHCP Option 43 configured (correctly)?

[vivek NAGAR]

As per attachment you have DHCP on WLC , do you use static capwap command to reach WLC? 

check the below blog for AP registration process will help you to understand

It turned out that the access point connected to the backup controller, although there are licenses on the primary controller. Changed the address to static, the access point is working on the network. As far as I understand, its operation time is limited by the license of the backup controller (evaluation).
