So I've been trying to use the connected and I've used ipconfig to get my IP address of my database and i've entered the following code to try and push a simple "hello" onto my database but I keep getting the message

Connecting...
Connection failed.

Here's my current code.

/**
* Example: Insert Example: Hello, MySQL!
*
* This code module demonstrates how to create a simple
* database-enabled sketch with inserting data.
*/
#include "SPI.h"
#include "Ethernet.h"
#include "sha1.h"
#include "mysql.h"
/* Setup for Ethernet Library */
byte mac_addr[] = { 0x90, 0xA2, 0xDA, 0x0F, 0x3A, 0xDC };
IPAddress server_addr(192,168,1,240);
/* Setup for the Connector/Arduino */
Connector my_conn; // The Connector/Arduino reference
char user[] = "ang";
char password[] = "";//myset password
char INSERT_SQL[] =
"INSERT INTO test_arduino.hello_arduino (message) VALUES ('Hello, Arduino!')";
void setup() {
Ethernet.begin(mac_addr);
Serial.begin(115200);
while (!Serial);
delay(1000);
Serial.println("Connecting...");
if (my_conn.mysql_connect(server_addr, 3306, user, password)){
Serial.println("Connected!");
my_conn.cmd_query(INSERT_SQL);
Serial.println("Data inserted.");
} else {
Serial.println("Connection failed.");
}
}
void loop() {
}
