AP is unable to join WLC 2504

[night143r]

Hello

Few APs are unable to join WLC 2504

Controller IP is 192.168.1.10

DHCP pool is made at cisco switch (192.168.1.0/24)

Laptop and AP are getting ip from DHCP but AP is unable to join controller

Also tried to give static ip to AP and told it controller IP but still issue is there

These messages  I am getting on repeat

Clear AP configuration then configure again and provide your master WLC IP on AP.

Check your time on the wlc, If  It's off so that is why the AP's are not joining ?

Is that all the info you can provide? 

We are all here trying to help, however, if the information needed are "confidential", then raise a TAC Case.

Hi,

Kindly share the fresh debug again & check on WLC trap log, AP should not be blocked.

Also check the available license and supported county and time zone on  WLC.

another AP with same model is registered with WLC?
