Answer 1

You probably have an error in your config with the host URL.
Here's a working example with a connection to a remote MySQL:
const mysql = require("mysql");
const connection = mysql.createPool({
host: "remotemysql.com",
user: "aKlLAqAfXH",
password: "PZKuFVGRQD",
database: "aKlLAqAfXH"
});
connection.query(
"SELECT hexcode FROM colours WHERE precedence = 2",
(err, result) => {
err ? console.log(err) : console.log(result[0].hexcode);
}
);
and here's one with mistaken host parameter:
const mysql = require("mysql");
const connection = mysql.createPool({
host: "WRONGremotemysql.com",
user: "aKlLAqAfXH",
password: "PZKuFVGRQD",
database: "aKlLAqAfXH"
});
connection.query(
"SELECT hexcode FROM colours WHERE precedence = 2",
(err, result) => {
err ? console.log(err) : console.log(result[0].hexcode);
}
);
The second one returns the same ENOTFOUND error.
Check if that's the correct URL, if the database can be accessed remotely and via which port you can use it.
