Unable to connect the VPN after upgraded the Forticlient VPN from 7.4.3 to 7.4.5 managed by EMS
Dear Team,
One of our customer upgraded the FortiClient version from 7.4.3 to 7.4.5 which is managed by EMS.
After that most of the users facing to connect the VPN.
By default, the FortiClient installer contains 9 VPN URLs or Gateway defined in EMS.
When the user tried to connect any of the VPN gateway by clicking 'connect' button it does not react anything.
For some users, the issue resolved by reinstalling the FortiClient, Re-register the zero trust telemetry with invitation code, restarting the laptop and connecting to different Wifi or network.
For few users, did not helped any of the above workaround.
From the user machine we collected the FortiClient log and found below logs.
Could any one help with below logs to sort out the issue.
