COMAPI WARNING: Unable to establish connection to the service. (hr=80080005) The issue is not with SCCM client or windows update agent rather it is more of a windows issue likely to be caused due to a missing/corrupt class in root\microsoft\windows\servermanager.
For this, you need to create a dump to analyze what is going on, and here is what you can find in the dump log.

When Windows Update is in the “scanning for updates” state, the WMI provider in use is ServerManager.DeploymentProvider.
To fix this problem you need to compile servermanager.deploymentprovider.mof. If the ServerManager.DeploymentProvider is bad, this command will fix it. If the ServerManager.DeploymentProvider is good, the below command will not cause any damage to the machine.
Open cmd in elevated mode (as admin):
- Loop: taskkill /f /fi “services eq wuauserv”
- Run the following command to recompile the MOF file: mofcomp c:\windows\system32\wbem\servermanager.deploymentprovider.mof
- Restart the machine.
After the server reboot, the software update scan went through successfully.
