When i check from %windir%\ccm\logs\WUAHandler.log, I saw the following error message:
"OnSearchComplete - Failed to end search job. Error = 0x8024401f."
"Scan failed with error = 0x8024401f."
After trouble a while and google, it suggest to enable Directory Browsing from IIS. So, I launch IIS manager and enable "Directory Browsing".
WUAHandler log does not has any error message after run the "Software Update Scan Cycle" from SCCM agent.
I ran "Software Update Scan Cycle" action for 2 computers, therefore, I can see the status for the 2 computer as below:
Good luck. :)
