I have a 100F device (6.2.8) setup for SSL VPN for remote connections using the VPN-only forticlient.
Windows works perfectly. MacOS does not! The VPN shows "Connecting" and then simply goes back to no message. There are no errors. The VPN does not connect.
Mac = Big Sur 11.4
Forticlient = 7.0.1.0060
- the VPN actually connects and authenticates. Logs show this. Also, putting in fake login details generates an client error for the wrong user/pass. The correct user/pass generates no messages. It connects but then for reasons unknown gets disconnected.
Check in Security & Privacy fortitray needs permission when you installed for the first time. If you cant see the application uninstall the forticlient using forticlient uninstaller and reinstall again. Check again in Security & Privacy > General. Allow fortitray app.
The process of installing and reinstalling FortiClient is flawed and from the first installation on, the others always end up resulting in the error reported in this post. The solution is quite simple, as it is about lack of permission, just go to System Preferences > Security & Privacy > Privacy and select Full Disk Access and give full permission to FortiClient. Voila, everything working.
