SSL VPN: Windows Works, MacOS does not!

Hi All.

I have a 100F device (6.2.8) setup for SSL VPN for remote connections using the VPN-only forticlient.  Windows works perfectly.  MacOS does not!  The VPN shows "Connecting" and then simply goes back to no message.  There are no errors.  The VPN does not connect. 

 

Mac = Big Sur 11.4

Forticlient = 7.0.1.0060

 

Facts:

- the VPN actually connects and authenticates.  Logs show this.  Also, putting in fake login details generates an client error for the wrong user/pass.  The correct user/pass generates no messages.  It connects but then for reasons unknown gets disconnected.

Im a bit stumped.  The VPN successfully connects but then gets disconnected for an error I cannot decipher.

TIA.

I had the same issue and this is how I fixed.

Check in Security & Privacy fortitray needs permission when you installed for the first time. If you cant see the application uninstall the forticlient using forticlient uninstaller and reinstall again. Check again in Security & Privacy > General.  Allow fortitray app.

 

I hope this is helpful.

So I guess when they mean "no support" they really mean it.

 

I gave up.  From my research, my conclusion is that the MacOS implementation is broken.  I ended up configuring the Cisco IPsec method and that works fine.  Its just a bit rubbish that I need to maintain 2 implementations now because of poor QA.

Someone give this man a beer!!  (assuming you are a man!)  This was totally the solution.    So so simple.    But at the same time, not easy to troubleshoot for the non-mac native.  Thanks very much.

If any developers from Fortinet read these forums, please, please, give more informative error messages. None of the errors indicated in the Forticlient log indicate any permission based issues.

 

Also, this could easily be solved by a permissions check within the Forticlient application and a dialog box that tells the client the EXACT reason it can't perform properly. If the 'fortitray' application doesn't have permissions, it should check and on failure tell the client via a message of some sort or (better) prompt them to remediate the problem by requesting the permissions again.  But why is this permission being skipped over in the first place? There were other permissions that the user received prompting to allow when the client was installed initially. How did this one escape?

It didn't work for me...!!! OS Monterey 12.4 and FortiClient 7.0.5.0166

The strange thing is that it doesn't matter if you put correct or incorrect values in the username and password, it always returns the same message, I think it doesn't even try to make the request to the server, it is stopped before by the certificate (which certificate? I have no idea).

Hi @FreddyE 

 

Were you able to solve this issue. Even I am facing the similar issue with no luck still.

@saqib_hussain  What version of macOS Mojave are you using and what is your Forticlient version. Are you using the VPN only client or the paid version.

doesnt work after the first installation there is no prompt asking for permission

Use IP address instead of hostname.
