FortiClient 6 and 6.2

Hello,

I used FortiClient 6.2 to connect to IPSec VPN on my Windows 10 PC. It was working for a few days. Today when I try to connect to VPN my internet access is gone and forticlient stops on "connecting" window (I can;t use outside internet and can't use local connection). When i click "disconnect" I can use Internet again.

I uninstalled 6.2 version and installed 6.0 version but it this same.

Please help me :(
