How to Fix ‘the L2TP Connection Attempt Failed Because the Security Layer Encountered a Processing Error’

An L2TP connection uses the Layer 2 Tunneling Protocol and is used mostly for supporting Virtual Private Networks. A Virtual Private Network(VPN) is used to mask the origin of connection by reflecting the connection over a server located in a different area than the origin of the connection. This can help many people to hide their locations from certain websites in order to bypass some security restrictions.

However, quite recently, a lot of reports have been coming in where users are unable to make a VPN connection and a “The L2TP connection attempt failed because the security layer encountered a processing error during the initial negotiations with the remote computer” Error is returned while trying to do so. In this tutorial, we will discuss the reasons due to which it is triggered and also provide viable solutions to fix it completely.

If you’re using a VPN, and get prompted with the Windows 10 VPN error 789 that states: “The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer” the causes may be within your system.

This error pops up when your system is not properly set up to connect to an L2TP server, thus the connection attempt fails even before you establish a connection with the server.

It is also linked to incorrect configuration of your operating system like Windows 10 in this case. This generic error is thrown when the IPSec negotiation fails for the L2TP/IPSec connections.
