Fixed | WSUS 2016/2019 | Error Code 0x8024401c | Windows 10 nor Windows Server 2016 reporting to WSUS

Problem:

I had recently had this error in WSUS where my Windows Server 2016 servers would NOT report into the WSUS Server. I would get an error stating 0x8024401c when manually performing a report now to the WSUS Server using:

Error from Windows Update on affected server

Solution:

Go to IIS Manager on the WSUS Server

Goto Advanced Settings of  WsusPool.

Make sure following settings are present/configured on the Pool, if not change it to below:

Make sure, the WSUS Entry in the Registry is having fully qualified domain name of WSUS Server.

NOTE: If you have Group Policy managing the WSUS Settings, then make sure you change the settings in the WSUS Policy to use the FQDN of the WSUS Server and run a gpupdate /force on the clients.
