I have googled this %DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 10.0.0.5:5246 and did ap cert expire command on wlc and other command, it didn't help
10 previous AP-s have succesfully joined this WLC, but this one, nope

Thanks in advance

check the link I share above

Yeah, i have just read it, so basically i should upgrade my WLC to newer image.
Because i don't have any other problem with flash except for:

%Error opening flash:/capwap-saved-config (No such file or directory)
%Error opening flash:/capwap-saved-config-bak (No such file or directory)

Raise a TAC Case and get the AP RMAed.  

The 5.0 Ghz radio is dead. 

This is a very common thing.  I have RMAed about 20 APs with dead 5.0 Ghz radios in the last 5 years.
