Microsoft said it is investigating reports of VPN connection errors after installing the Windows 11 April 2024 update.
Security update KB5036893 was released on April 9 for all supported versions of Windows 11, and some users reported that VPN connections with TPM-backed certificates did not work after when installing the patch.
VPN connections will be affected by update KB5036893 for Windows 11.
Reddit user Flo-TPG said the Windows 11 update caused a “cannot find certificate” error when trying to use a VPN connection. Shortly after, Microsoft warned that VPN connections may fail after installing this April 2024 security update, and the company said it was “investigating user reports and will provide provide more information in the coming days.”
The only workaround currently is to uninstall update KB5036893. In that context, Microsoft says that it is planning to release a solution “in an upcoming release,” which suggests that a hotfix will be deployed soon.
Users are advised to temporarily remove KB5036893 if they want to use VPN.
This latest VPN issue comes nearly a year after Microsoft had to fix major speed issues affecting L2TP/IPsec VPN connections in Windows 11 caused by a bug fix. The company has a Windows Insider program designed to detect bugs in early versions of Windows updates, but security patches can often cause unexpected problems like these VPN problems.
