Hello,

The error message “The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer” indicates that there may be an issue with the Layer 2 Tunneling Protocol (L2TP) VPN connection.

Check VPN Server Configuration: Ensure that the L2TP VPN server is properly configured and supports the security settings you are attempting to use. Verify that the server’s settings match the client’s settings.

Turn off firewall to check.

Verify Network Connectivity: Check the network connectivity between the client and the VPN server. Issues such as packet loss, network congestion, or routing problems can affect the negotiation process.

Consider Alternate VPN Protocols: If troubleshooting L2TP continues to be challenging, consider using alternate VPN protocols such as IKEv2 or SSTP, which may offer better compatibility and security in some scenarios.
