FortiClient VPN not connecting after upgrade to Windows 11

I connect to my Fortigate Network via the FortiClient VPN. Never had an issue on Windows 10, but since I upgraded to Windows 11, it will no longer connect.

Hi All

The error message states I need to check my shared vpn key/ user and password, however I can 100% confirm these are correct.

Info:

- System: Windows 11 Home (Pro does not work either)

- FortiClient version 7.0.0.2

- VPN Type: IPSec VPN

I haven't got the logs to hand but they stated the remote end point did not respond?

Anyone else had issues since upgrading to Win 11?
