Forticlient 6.4.1 on macOS 11.2.1 with Fortitoken issue

Hi 

Does anyone know if there's a recorded issue with the above set up? I have one connection using the above that has MFA using fortitoken and I get the challenge for a token code and this connects when I enter the code, stating the VPN is connected successfully. I can't connect to or ping anything either internally on my business network or anything externally like 8.8.8.8.

The other connection I have doesn't use MFA but is the same client and macOS (it's the same machine!) and it works fine. 

Anyone else out there finding this/resolved it?

Thanks

Rikki
