Hi @Boopathi Subramaniam ,
Perform the below steps if we are noticing the Failed to Add Update Source for WUAgent of type (2) message in WUAHandler.log.
1.On the client computer, go to C:\Windows\System32\GroupPolicy\Machine.
2.Backup the Registry.pol file to a different folder or simply rename it, something like Registry.old.pol.
3.We may also delete the Registry.pol file from the machine folder.
4.Restart the SMS agent host service(SCCM client agent service-CCMEXEC) and that should fix Error
5.Finally re-run the Software Updates Scan Cycle in the Configuration Manager Actions tab.
Here is the detailed article we could refer to:
