AP not joining Controller

[oyenibi4lv]

Please i need assistance, i have some AIR-LAP1131G-A-K9 that is not joining the controller. I'm currently using Cisco4400 series controller.

Note: the AP's are getting IP address via DHCP as the controller and AP's are on same subnet. from the AP, i can reach the controller's AP-manager IP and Management IP.  see below error message from the AP.

*Mar 1 00:00:48.706: %LWAPP-5-CHANGED: LWAPP changed state to JOIN

*Mar 1 00:00:54.706: LWAPP_CLIENT_ERROR_DEBUG: spamHandleJoinTimer: Did not receive the Join response

Thanks @Leo Laohoo  some of the AP's came up after setting the time to a recent earlier time when the certificates were still valid.

i will proceed to upgrade software if this will fix completely

 - The particular ap-model is very old and will usually not be compatible with later software releases, switch to modern ap model is adviced
