Tried all the ideas, but nothing VPN will almost always drop within the first hour of use - leaving only a full PC reboot before it will allow re connection.
Tried Disabling and re-enabling NICs - waiting for a while etc etc. It happens to many of my colleagues Home working windows sessions too. Its just unreliable and nothing in the logs seems to help show the actual error to me.
I see this is 4 years later and I have been having the same problems - symptomatically speaking. Got FortiClient 6.0.4.0182 running on a Win 10 Pro v.1803 (build 17134.1130) x64 Dell Latitude 3590 machine and for several months now the FortiClient is unusable - it disconnects the internet connection immediately. As I use FortiClient seldom, I cannot pinpoint the time, nor correlate with any OS update or anything else in the system.
The link mentioned above points to older versions of FortiClient. I wonder, do you have any more recent builds or any new advice to help me resolve this problem?
