WSUS update server not updating clients (Server 2019)?

Question

Hi ,
we have WSUS and different servers in our network.
Windows 2019 does not automatically connect to the WSUS server.
WSUS Server (Windows Server 2022),
This was reinstalled to rule out errors here (previously Windows Server 2016)!
Windows update log from windows server 2019
Date of last check 07.02.2022 > there was a manual search

Regards
Wolfgang

Answer 1

the systems are running 24/7

Answer 2

You currently have it set to run updates during the maintenance period of the system. Are the systems on when the maintenance period hits? I'd recommend turning off the AutomaticMaintenanceEnabled to force it to happen on your schedule.

Get rid of "AllowMUUpdateService"=dword:00000001

That's a WUfB policy.
