MAA software update may fail with "HTTP 599: server certificate verification failed" error message if the system clock is way off from the current date and time.
Confirm if the date and time is correct. If date and time are not sync, please follow the steps in 000008833, and confirm if the issue is resolved.
If the issue still persists after clock is synchronized, you will need to contact Blue Coat Support for further investigation.
