Unclean disconnect with IPsec VPN

[tola]

Hi,

I have multiple VPN connection installed in my machine. Some are windows native VPN connections and some Forticlient VPN connections. Forticlient version is 7.4.3.1790. Operating system is Window 11 with latest updates.

When i connect Forticlient IPsec VPN disconnect it and try to connect Windows native L2TP/IPsec VPN, it does not work, but returns error:
The L2TP connection attempt failed because the security layer encountered a processing error during the initial negotiations with the remote computer.

I found out, that windows VPN starts working again, if I stop "IKE and AuthIP IPsec Keying Modules" forcibly with command:
$ net stop "IKEEXT"

So is there some kind of "unclean disconnect" bug in Forticlient? Or could this be fixed with proper settings etc?
