Refer to the exhibits. The SSL VPN connection fails when a user attempts to connect to it. What should the user do to successfully connect to SSL VPN?

The SSL VPN connection failure, especially if it's a "connection refused" type error, often indicates a mismatch between the port the SSL VPN server is listening on and the port the client is attempting to connect to. The exhibit would show the FortiGate SSL VPN configured on a specific port, and the client error would imply it's trying a different, incorrect port, necessitating a client-side port change.

Changing the server IP address on the client is typically unnecessary unless the initial IP address provided was completely wrong, which would usually result in a "host unreachable" or "DNS resolution failed" error.

Changing the idle-timeout setting on the FortiGate primarily affects how long inactive sessions are kept alive and does not directly resolve initial connection failures.

Changing the SSL VPN portal to the tunnel mode on the client is a configuration choice for how the VPN operates after connection, not a solution for initial connection failures.
