FortiClient console crashes after choosing a certificate for a VPN

[Bruce42]

Windows 11 (intune enrolled), FortiClient 7.4.0.1658.

If I setup a VPN that doesn't have a certificate associated with it, I have no issues.

But if I associate a certificate with a connection, about 2 seconds later the console crashes. If I open it up again, it will crash a couple of seconds later.

It doesn't log an error at the time it crashes.

I have to uninstall and reinstall again to get it stable again but can't associate the connection with a certificate.

Anyone got any thoughts?

Can you try older version like 7.2.x or 7.0.x?

Hi AEK, I had 7.0.11 on here working fine but Tenable reported it has a vulnerability (PSIRT | FortiGuard Labs, Low severity, but I was under pressure to mitigate it) so I upgraded and all I seem to be able to download is 7.4. I'd be happy to try 7.2.2 or greater but do not see a way to download it.

Hello Bruce

You can download it from support portal, then go to Support menu > Firmware download, then select FortiClient > Download > 7.0.x or 7.2.x.

If you download the latest patch, i.e.: 7.0.13 or 7.2.5 then it should be the most stable and vulnerability free.

Thanks AEK

I don't have access, but I've pinged the guy who does and will give 7.2.5 a try. Thanks.

But it would still be good to know what is going on with 7.4 given that is the one that is readily accessible.

You're welcome Bruce

7.4.0 is the first release of this version (patch zero), and it is usually normal to have many bugs in all new releases. As patches are released more issues are fixed and it should be more stable.

Unfortunately, 7.2.5 is doing the same thing. Installs fine, works fine if none of the VPNs configured use certs but as soon as a VPN with a cert is configured, the console crashes and continues to crash a few seconds after it is restarted each time.

Hello Bruce

Is it FortiClient or FortiClient VPN (the free version)?

[AEK]

Also can check if you find anything useful in Windows events?

On the other hand I tried FortiClient VPN 7.4.0 on Windows 10 and it doesn't crash when I set a certificate.

I've tried both the paid and free versions of 7.2.5 now and both crash. Nothing is appearing in either the Application or System event logs.

One of my colleagues has tried the free 7.4.0 on his machine which is a similar build to mine and his not experiencing any issues. Working out exactly what might be different / relevant isn't getting us anywhere.
