Commented Unassigned: Windows Server 2016 [376]

Hello,

I have a Windows Server 2016 with an installed WSUS.
I also use WPP on this Server.
When I try to import Updates to WSUS and display it in the WSUS-Console I get error 40.
In the debug Log I can see it trys to connect to the 2003/2008 WID not the actual WSUS WID np.

The WSUS-Console is Version 10.
How to fix this?

Thanks for your help
Markus
Comments: I updated the WSUS Server from 2012 to 2016 to try if it works I use to old certificate, I used before. Do I have to reimport it?
