Hello everybody,
You're the only hope left for me because I've tried everything to get Forticlient VPN work on W11.
So I'm using a IPsec connection with pre-auth key, downloaded latest version of Forticlient but it stills says that error occured.
I'm 100% sure that login details entered are correct as it works with no problems on netbook with W10 installed.error

Any help will be HIGHLY APPRECIATED.

There is no fundamental changes in Windows 11, so existing application should work.
Windows 11 is only supported on FortiClient 7.0.2, per documentation:

Now, do you see any difference when using Ethernet port vs. Wifi?

Hello, thank you for the reply!
You may have good lead, I've switched from Ethernet port to WiFi (external card, cause I've PC) and it connects without troubles!
Any idea how can I make it work on ethernet cable too?

Not quite sure, unfortunately. The wifi/cable difference was noted in FortiClient 6.4
The fix was not related to FortiClient, and customer didn't say. Someone from FortiClient team may assist, or maybe open a support case

Also, check if you can change the local peer ID:
