The reason this happens is that although the publishing service and the SUP/WSUS is most likely configured to use a proxy. The WSUS API we call uses the Windows Crypto API for the timestamping operation to http://timestamp.digicert.com. The Windows Crypto API uses the default proxy configured at the SYSTEM level not what is defined in our publishing service or WSUS. We have confirmed with the SCCM product group this seems to be a known scenario where the WSUS API uses the default HTTP proxy setting in the SYSTEM level context, not the proxy configured in WSUS. Since the SYSTEM proxy is usually not set, this is why the HTTP call to http://timestamp.digicert.com will return the error(s) listed above.

Setting the SYSTEM Proxy:

To set the SYSTEM level proxy, we've found it's usually easiest to set it using Internet Explorer and PSEXEC.exe.

• Download PSEXEC.exe from https://live.sysinternals.com/ (https://live.sysinternals.com/)
• Open command prompt as Administrator
• Launch Internet Explorer as SYSTEM using command line: psexec.exe -s -i "C:\Program Files\internet explorer\iexplore.exe"
• In Internet Explorer > Settings > Connections > LAN Settings > Enable "Use a proxy server for your LAN and configure the IP Address and Port and click OK and close IE
• If psexec.exe is blocked in your environment, you can create a one time scheduled task that must run under SYSTEM/COMPUTER account context and set the SYSTEM level proxy using netsh. You can run the following command line: cmd.exe /c netsh winhttp set proxy http://myproxyserver.com:8080 (where the server name and port are set for your environment)
• Run the publishing service sync again and see if the publishing process works.
• If you still have issues publishing updates, please send us a support request via email https://patchmypc.com/technical-support or post a topic to our forum https://patchmypc.com/forum/index.php?board=23.0
