Forticlient SSL VPN not working on Ubuntu

Hi all,
I've installed the last version of Forticlient (7.0.0.0018) on my Ubuntu virtual machine (version 20.04.3)
 
I've setup a SSL VPN, but it's not working, I've receive two errors:
  • [sslvpn:EROR] vpn_connection:706 IO read remote failed: timeout
  • [sslvpn:EROR] vpn_connection:1379 Error: Disconnected because of error: Read packet from tunnel
With the same credetials and settings I'm able to connect on a Windows machine
 
Anyone have encountered these errors? How can I fix the connection?
 
Thanks in advance,
Jack

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.

Hi boheee,
thank for your answer
 
I've tried openFortiGUI too and I'm able to connect to the VPN, so I think the problem is the official client
 
Which version of FortiOS do you have? I've a Fortigate 90D with FortiOS 6.0.12
 
Regards,
Jack

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.
