We are running Server 2016 with WSUS version 10.0.14393.2636. Up until 2 days ago, all was working as it should. Starting yesterday, synchronization started to fail and the console would crash when I clicked on Synchronizations (at 44%). I used SQL management studio to connect to the Windows Internal Database and cleared out the synchronization history. Now i can I can open the synchronization pane but it will not synchronize. I have made all of the IIS tweaks recommended in other posts to include:
Queue Length - 25000
CPU Limit Interval - 15
Service Unavailable response type - TCPLevel
Failure Interval - 30
Max Failures - 60
Private memory limit - 4096000
I am receiving Event ID 10022. The last catalog synchronization attempt was unsuccessful.
In the WSUS console, I see the following error: The upstream server experienced an unexpected error. Try again later. the synchronization details are as follows:
SoapException: Fault occurred

We do not use a Proxy server and we are not getting any drop at our firewall.
I have run a server cleanup both through the GUI and PowerShell
I don't really want to uninstall and reinstall but I will if that is the only option.
Not sure where to go from here. Any help would be much appreciated.
