Recent Windows update results in VPN Connection issue

Two recent Windows updates contain some bug fixes and improvements. But at the same time, some users reported that these two updates break their VPN connection. This is a VPN bug.

When you try to connect to a VPN on your computer, the attempt may fail with an error message as follows:

Can’t connect to VPN. The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.

This issue mainly affects the built-in Windows VPN client when connecting to Ubiquiti Client-to-Site VPN, SonicWall, Cisco Meraki, and WatchGuard Firewalls.
