So for whatever reason on new devices that we have set up the past couple of months we cannot seem to connect to our VPN at all on these new devices. However, the older devices seemingly have no issue. We have tried reinstalling the C++ libraries, reinstalling FortiClient, and updating the NIC driver but have had no luck.
All of these new devices are running Windows 11 Pro 24H2 and its a mix of 2 Dell Latitude laptops and one Microsoft Surface Pro 9 if that helps with anything. Also tried looking for some of the older versions on the support page but we don't have the firewall tied to our account so it doesn't let us search through the download page. I have tried version 5.4.3.0870 of FortiClient that we had saved but that didn't work either although I am not sure if that version is Windows 11 compatible or not.
Not sure where to go from here any help is appreciated!
Solved! Go to Solution.
Here is what the configuration looks like in FCT I am not sure if some default settings got changed in a recent FCT update or if there were changes made to our FGT but usually in the past we could just keep the defaults and not worry about anything besides the gateway and key.
The changes I made are the items circled in red:
All i have to say is why. I created on a Fortigate 80e with the latest firmware as of 6/10/25 a vpn for a forticlient, downloaded the latest forticlient and it takes finding this post to get it working. Just dumb.
