Hi Mohamad,
Please SSH into the AP and check if you are able to ping the controller IP address.
Also set the controller IP manually on APs and also make sure that port 443 and 22 are not blocked between AP to controller network path.
set scg ip xxx.xxx.xxx.xxxAlso try to login into the controller CLI and disable the AP cert check and see if it helps.
