FortiClient 6 and 6.2 can't connect, drop Internet


I used FortiClient 6.2 for a few days and all works fine. Today I tried to connect to IPSec VPN and my Internet access was gone (and FortiClient still was connecting to VPN). I was not able to use local connection and outside connection. When I clicked "disconnect" button Interned came back.


I uninstalled it and installed FortiClient 6.0 but without any change. Still can't connect to VPN and use internet while forticlient try to connect...



Please help.

Please help :(

I found in logs:

I am having this same issue with exactly the same error showing up in the log. I never changed anything with my network (i.e. home modem and router are unchanged) and I get this on both my win10 desktop and a macbook pro. I have talked to my ISP but all they do is have me reboot the router and punt me saying "it's a software issue."


On the server side, there are absolutely no logs showing connection attempt or anything from my IP.


edit: actually, I was wrong... my Macbook IS connecting without issue. So, makes me think this is an issue on Windows 10.
