Тепер вони викотили апдейт, який ламає впн в Він 10: https://www.reddit.com/r/sysadmin/comments/s1oqv8/kb5009543_january_11_2022_breaks_l2tp_vpn/
As the title says. Just rebooted two Win10 laptops that installed KB5009543 & KB5008876. Now their L2TP VPNs to different sites (All SonicWalls) are not working. "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer".
There's two other confirmed reports in the Windows 10 subreddit.
I uninstalled KB5009543 and now my L2TP VPNs work again.
