Problem during connecting with disconnecting last connection when is allowed only 1 at time via cli

[ldrahnik]

Hello,

I connect to the VPN with the command below usually and it works fine but when I am disconnected because for example connection problems and the last connection persisted on the server and server allows have only one connection at time I am not able to use the same way how to connect. Why? Because displayed popup:

You already have an open SSL VPN connection. Opening multiple connections is not permitted. Do you want to proceed and disconnect your other connection?

is displayed for like second and immediately is hidden. Command log:

```

$ /opt/forticlient/forticlient-cli vpn connect MyVPNName

Connect VPN: MyVPNName
Status: Connecting...

DONE.

```

I tried to add `--auto-connect` but it was not helpful. Anyway I can confirm using GUI it works, I mean when I answer to (not missing) popup yes and confirm disconnecting the previous connection.

```

Because it looks like it asks twice:

```

Confirm (y/n) [default=n]:Confirm (y/n) [default=n]:

```

I tried it solve using `expect`:

```

#!/usr/bin/expect

set USER [lindex $argv 0]

set PASS [lindex $argv 1]

spawn /opt/forticlient/fortivpn connect MyVPNName --user=$USER --password

expect {

    "Password:*" { 

set timeout 1

send -- "$PASS\r"

expect eof

    }

}

```

And it works. How I understand why `expect` works: `expect` uses `spawn` which creates a process in the background and with `set timeout 1` then after autocompleting the password is process left in the background and because of that is not cancelled GUI popup question.
