FortiClient stops connection

[Netsec42]

Hey there,

we have the following problem with one of our Mac systems.

Forticlient 6.4.1 is installed and works on the same day when the CLient is freshly installed. The next day the connection via SSL VPN is no longer possible, when dialing in the message pops up : network error.

But if you reinstall the client and create the VPN profile again, the dial-in works fine again. This happens since 5 days and a solution from our side has not been found yet.

The Mac OS version is 10.14.6, the Fortigate is a 300E with firmware v6.4.0, the same happens with the Forticlient version 6.4.0.

Attached is a log file that hopefully shows the problem
