Hi Jack,

I am using the fortiOS from aws marketplace. Previously i was using the FortiOS v6.4.4 build1803 (ubuntu forticlients doesn't work) and i thought that it could be fortiOS. So i upgraded my fortiOS to FortiOS v7.0.1 build0157 (GA) (THIS IS THE LATEST PATCH).

Forticlient still does not work...

I actually have plans to purchase their forti-tokens to have 2FA for my forticlient but ubuntu forticlient cannot even work. I have been looking for solutions for ubuntu forticlient to get it to work but to no avail.

Hi, I am having the same issue as well. Updated my fortigate to latest version and still unable to connect using Forticlient 7.0.1/ 6.4.4. The only way to connect in is to use openFortiGUI (https://hadler.me/linux/openfortigui/)...

However, I still wish to use official forticlient and so far it is not working. I have tried contacting support but they said it's my network/configuration setting.

I started a whole new VM of fortigate with no configs, only a SSL VPN setup and was also unable to connect in via forticlient.
