Question:
Access to sql Fiware

Description:
I have a problem with sql access from the fiwarelab machine.
I have duplicate the same as in fiwarelab in local, by code I have designed a graph to show the sql data.

As I said in local if I work correctly, but when I make the query to the machine of fiwarelab I can not show the graphs, nor the errors that I have programmed for a bad connection.
I'm somewhat lost with the fiwarelab theme
Do I have to open the ports or change some configuration of sql?

This is one of my codes:

function conectarBD(){
$server = "localhost";
$usuario = "root";
$pass = "";
$BD = "ual";
//variable que guarda la conexión de la base de datos
$conexion = mysqli_connect($server, $usuario, $pass, $BD);
//Comprobamos si la conexión ha tenido exito
if(!$conexion)

//devolvemos el objeto de conexión para usarlo en las consultas
return $conexion;
}

Greetings and thank you.
