Forticlient 7.4 - Stuck at connecting and MFA/fortitoken not prompting on reconnect

[shamalpha]

After we upgraded Win10/11 clients to the Forticlient 7.4 version, we experienced the forever connecting issues like others. Additionally, we found that after supplying the fortitoken on the first connection, the subsequent attempt did not prompt for a token/code. This was repeatable behavior on the 7.4 client and occurred after an immediate reconnect and rebooting before reconnecting.

We worked with support to troubleshoot and found that backing down to Forticlient 7.0.13 resolved the connectivity and token issues. We do not pay for client support so our tech was unable to reach out to the client team on this MFA/token issue. 

Has anyone else experienced this behavior in Forticlient 7.4?

Reinstalling the redistributable did not help with these issues either.

Hi @shamalpha,

Is it possible to share the debug outputs or ticket number? I want to see if FortiGate did send a token request. If it is a FortiClient issue, you can try a different FortiClient version.

I sent you a message with the ticket number

Trying installing this Visual Studio Redistributable: https://aka.ms/vs/17/release/vc_redist.x64.exe

The Forticlient VPN Application is trying to start fortitray.exe, but it needs a .dll file to work (mfc140u.dll) which is missing from Windows.

After installing and a reboot, your Forticlient VPN app should work again.

I got 7.4 to work on my Windows 10 Pro Machines. Cannot get it to work on Windows 10 Home. I know remote desktop doesn't work on Home. Is it the same for Fortinet Client?
