On our clients we use FortiClient (Version 5.4.2.0860) with the same (matching) configuration.
We have about 20 employees who use Client VPN. 10 of them have no problems, the other 10 have disconnections on a regular basis and then have to login again.
Interestingly, there are sometimes in between, sometimes for hours, no crashes.
AutoKey Keep Alive I have not activated yet.
I think the problem is by the clients.
We use Microsoft Surface 4 Pro and HP Notebooks.
Has anyone had any experience in the matter and how did you solve it.
In windows 7, I solved the same problem the deleting the Fortissl connection in internet options of windows control panel.
thank you for your reply. I will test it.
