I’m using Duo for 2fa on Fortinet FortiGate SSL VPN. I installed the radius proxy and it works all right. By accessing the VPN via the web, I receive the error message:
“The SSL-VPN host-check Java applet cannot be loaded. Please check that you have Java installed and enabled.”
Access to the VPN is therefore denied, but with the other vpn portals that do not use radius, this does not happen.
