Post the complete output to the following commands: 

1.  WLC:   sh sysinfo; 

2.  WLC:  sh time;

HI,

In addition to the commands mentioned by Leo, if you still cannot register, you can collect the following debug information:

WLC debugs:
WLC> debug mac addr < AP MAC address >
WLC> debug capwap errors enable
WLC> debug capwap events enable
WLC> debug dtls all enable
WLC> debug pm pki enable
To disable debugs: debug disable-all

AP debugs:
AP# debug capwap client event
AP# debug capwap client error
AP# debug capwap client detail
AP# debug dtls client error
AP# debug dtls client event
To disable debugs: u all
