Client VPN not connecting on Window 11

[Bhardwajvishnu]

We are currently configuring Client VPN on an MX67 appliance. However, we are unable to establish a connection on our windows laptop (Win 11) not only on single but on  multiple Windows laptops.

We have attempted to troubleshoot using the official Meraki documentation (linked below), but the issue persists.

• Error Message: Error code 691, 789 etc.

• Documentation Reference: https://documentation.meraki.com/SASE_and_SD-WAN/MX/Troubleshooting_and_Support/Troubleshooting/Trou... 

Could you please review this and suggest a resolution?

The error messages for Windows built in VPN are usually pretty generic.

Ensure that your VPN configuration is set as per the Meraki documentation:

https://documentation.meraki.com/SASE_and_SD-WAN/MX/Design_and_Configure/Configuration_Guides/Client...

In particular, verify that PAP is enabled and the credentials are correct.

If this is a new deployment, I'd suggest looking at migrating to AnyConnect/Secure Client VPN which is a superior product and still integrates directly with the Meraki MX

Try using my wizard to configure Windows for the client VPN.

Try running rasphone.exe, and making the connection with that.  It gives better error messages.
