As i have configure client VPN on MX68 but when i am going to connect it through Windows then i show an Error "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiation with remote computer".

I have tried all possible thing link removing security updates. reconfigure VPN on Client machine but issue is as same.

Hi @Ubaidkhan,

Removing the new update has resolved this for all the customers.

Hope the client configuration is correct as per the documentation

https://documentation.meraki.com/MX/Client_VPN/Client_VPN_OS_Configuration

How about reaching Meraki Support?

Hi @AjitKumar 

I have uninstall updates and i have configured client as per Meraki document but issue still the same.

I haven't reach Meraki support.

I had same issue with windows update KB50009543 was braking vpn client. After uninstall and rebooting, then adjusting network adapter setting for client vpn, everything was good to go.

@Ubaidkhan If removing the update and following Kbase article hasn't helped I would contact support, its probably something simple that they could guide you through over the phone.
