I bought two Lenovo Thinkpad X13 Gen 6 laptops two months ago. Neither of them can use VPN with Foticlient. Meanwhile, other company laptops like the Dell 3450, Acer P4/P6, and Thinkpad T14s can all use it. I'm certain the preshared key and username/password are correct. Please help me fix this error. Only these models are affected.

Hello,

Please share the below info:

What is the VPN type? SSL or IPSec Dial Up

What is the version of the FortiClient you are using?

Also, share the KB version of Windows..

Thank You

7.4.2 has several known issues. Try 7.4.5 instead, or if you are using the free version then try 7.4.3.

Can be related to the NIC driver. You can verify this by connecting via a different network card.
