How I "force" a Cisco AIR-AP1852I-B-K9 to Join WLC?

I have a refurbished AIR-AP1852I-B-K9 that I am trying to join to a 2500 WLC. This is number 2 of the 2   we ordered. The first one joined on its own no problem without any intervention from me, this one is being stubborn.

I keep seeing this message:

[*12/18/2017 12:50:19.8397] Discovery Request sent to X.X.X.X, discovery type STATIC_CONFIG(1)
[*12/18/2017 12:50:19.8497] Discovery Request sent to 255.255.255.255, discovery type UNKNOWN(0)

I set the first IP (capwap ap primary-base <wlc name> <wlc ip>) but do not know where the other one came from. I see the clock is off and am not sure if that is contributing to the issue or not.

I have tried just about everything I can think of including multiple factory resets, statically assigning an IP and updating code. (which failed) I am now am out of ideas unfortunately.

I can see the AP as a CDP neighbor on my switch so we make it that far. It also pulls a DHCP address. We do not use option 43 so pointing the AP to the WLC should work.The CLI is limited on these compared to what I am used to working with also.

Any ideas?

Hi,

Is the AP got IP address from DHCP?

Yes, it pulled an IP from the pool. We do not use option 43 so naturally I  statically assigned the controller for it to to join.
After that did not work I did a factory reset and statically assigned an IP and the controller IP.  That also failed.

Turn out there was a license issue on the WLC itself, we reached max AP count.  Upon review of the logs I saw the message staring me in the face.  Thanks for the help guys!
