ERROR when trying to access my managed Database Droplet

Hello, I imagined that my managed droplets will be easier to use but I’m getting errors on PostgreSQL and mySQL.

server.js

const http = require("http"), port = 8080;

const mysql = require("mysql")

const conn = mysql.createConnection({
        host: "db-mysql-ams3-12003-do-user-4780354-0.db.ondigitalocean.com",
        port: "25060",
        user: "douser",
        password: "p6ht9qa28lns7czv",
        database: "defaultdb"
})

conn.connect(function(err){
        if(err) console.log(err)
        console.log("connected")

})

const requestHandler = (req, res) => {
        const url = req.url.slice(4)
        res.end(url)
}

const server = http.createServer(requestHandler)

server.listen(port)
