Forticlient IPSec VPN Connectivity Issue.

[Abu_Ryan]

Hi Team,

I'm facing an issue with FortiClient VPN at one of my client sites and would appreciate some help or insight.

We have been using the free version of FortiClient 7.4.2, and it's working perfectly fine for IPSec remote VPN connections. However, as per the client's request, I recently installed FortiClient version 7.4.3 (free version) on two new PCs. After installation, when trying to connect to the VPN, the FortiClient application closes automatically without completing the connection. Is this a known bug with 7.4.3? Are there any patches or configuration changes required for the free version?

Any help would be greatly appreciated.

Thanks in advance,
Aslam.

Hi Aslam

Start by double-checking if the IPsec config on FCT 7.4.3 is the same as on FCT 7.4.2, and is matching the config on the remote FGT.

Hello,

I would suggest to check the phase1 and phase2 config.
