Forticlient VPN - Zero Trust Fabric Agent

[vz]

HI support, I hope all's well on your side of the world.

So here’s a bit of background;

In order for our users to connect to the company vpn:
1) They need to be added to a vpn member on Active Directory ( Synced changes thereafter)
2) Have SSL-VPN configured with the remote gateway and custom port 10447
a. VPN Version 7.4.0.1658 for all at the moment
3) Authentication: Prompt on login
4) Client certificate: prompt on connect
5) Nothing further

For some strange reason, on one laptop, my creds work just fine, but on another laptop, it does prompt to accept the certificate BUT it fails with an error message: Permission Denied -455.

Any advice on what I can check would be appreciated

Thank you.

Kind Regards.
