Windows 11 22H2 update, FortiClient VPN doesn't work

[costasd]

Hello,

Today I updated Windows 11 to the new version (22H2) on 2 PCs. FortiClient VPN worked seamlessly on the previous version (21H2) but after the update it doesn't connect and gives the following message:

Is it a known issue with FortiClient VPN? Is there a solution?

Thank you in advance,

Costas

This finally was the fix for me as well!  THANK YOU JAMES!

That worked for us. Thank you James!

My way of resolving this:

Uninstall FortiClient

Restart

Run:

ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh int ip reset
netsh winsock reset

Restart

Install the latest FortiClient version (preferably offline installer from firmware page)

Thanks. I gave it a try but no luck. The IP address is still not passed over to the Fortinet virtual adapter.

Try FortiClient 7.0.2.

Just had same issue, downgrading Realtek driver still didn't work. But this version worked on Windows 11.
