## MICROSOFT INVESTIGATING VPN CONNECTION FAILURES AFTER WINDOWS 11 UPDATE
Microsoft is currently investigating reports of VPN connection failures that have occurred after installing the April 2024 Windows 11 update. The security update, known as KB5036893, was issued on April 9th for all supported versions of Windows 11. Some users have reported issues with VPN connections using TPM-backed certificates following the installation of this patch.
## USER REPORTS ERROR MESSAGE FOLLOWING WINDOWS 11 UPDATE
According to a Reddit user named Flo-TPG, the Windows 11 update has led to an error message stating “a certificate could not be found” when attempting to establish a VPN connection. Microsoft has issued a warning regarding potential VPN connection failures after installing the April 2024 security update. The company reassures users that they are actively investigating these reports and will provide further information in the coming days.
## UNINSTALLING UPDATE AS TEMPORARY SOLUTION
As of now, the only workaround for users experiencing VPN connection issues is to uninstall the KB5036893 update. Microsoft has indicated that they are working on a resolution for this issue, with plans to release a hotfix in the near future.
## LATEST VPN ISSUES ADD TO A YEAR OF CHALLENGES
These recent VPN issues add to a series of challenges faced by Microsoft in the past year. Previously, the company had to address major speed issues affecting L2TP/IPsec VPN connections in Windows 11 following a problematic update. Microsoft’s Windows Insider program is designed to detect bugs in early versions of updates, but even with this system in place, security patches can sometimes lead to unexpected issues like the current VPN incidents.
