I can't connect to de VPN server after the windows update.

The L2TP connection attempt failed because the security
layer encountered a processing error during initial
negotiations with the remote computer.

That is the message that I get. The windows version is Windows 10 version 1809.

@hwdsl2 commented on GitHub (Dec 17, 2018):

@Tjird Re-apply the fix for Windows Error 809 and reboot. See [1]. This error could also indicate that the connection attempt did not reach your VPN server [2]. In addition, try deleting and re-creating the VPN connection [3], double check to make sure the VPN credentials are typed correctly.
