The SSL VPN is configured to listen on port11443on the FortiGate device, as shown in the SSL VPN settings in the exhibit. However, the user is attempting to connect to the server using port1443, as displayed in the VPN connection status. The mismatch between the ports is causing the connection failure. To resolve this, the user should change the client configuration to use port11443to match the FortiGate SSL VPN configuration.
