Hello Team

After I installed the following update

2022-01 Cumulative Update for windows 10 Version 21H2 For C64 based System

KB5009543

My mobile VPN IKev2 stop working with the following error "General processing error" 

From the Event Viewer

"CoId={E015629F-0797-0001-B6F6-15E09707D801}: The user SYSTEM dialed a connection named WG IKEv2VPN which has failed. The error code returned on failure is 13804.:

After uninstalling the update I was able to connect with no issues.

Answer 2

Before seeing your post, i updated it already. KB5009566 was successfully installed on top of Windows 11 22000.376 and old build number is changed to 22000.484

Answer 3

I can confirm this same issue after installing KB5009566 on a Windows 11 System.. The only way I've found so far to resolve the VPN issue was to remove the update. This happens on both Windows 10 and Windows 11 systems.

Thanks for the report. It is now in the Media too:

New Windows KB5009543, KB5009566 updates break L2TP VPN connections (bleepingcomputer.com)

Consider pausing the updates in the meantime.

Answer 5

KB009543 appears to have broken storage spaces - configured as redundant drive after the update the drive appears to the OS as raw unformatted. Uninstalling the update restored the drive. This is disappointing as I had the drive configured as redundant/two-way mirror because it holds critical data.
