Forticlient blank screen Ubuntu 18.04

[dmain]

Followed the instructions to install from https://www.forticlient.com/repoinfo and also tried installing directly from the .deb file at https://www.forticlient.com/downloads. In both cases, whenever I launch the app, the screen is blank. Launching from the commandline, all I see are 2 lines:

Starting FortiTray Platform detected: ubuntu

Does anyone have any suggestions?

If the official client does not work for you can try the open source client openfortivpn , only for ssl vpn

Check that fortivpn service is running and directory /var/lib/forticlient exists

Hi, to check whether the Forticlient service is UP & running

# systemctl status forticlient.service

If it is stopped, you can try to start it with following command.

# systemctl start forticlient.service
