Please help me how to resolve this issue if anyone knows. Thank you.

I'm using a vServer from Ionos for a little project. I installed a MariaDB and NodeJS. Currently I'm trying to connect them both. Here is my code:
const mariadb = require('mariadb');
const pool = mariadb.createPool({
host: 'localhost',
user:'root',
password: 'xxxxxxxxx',
database: 'christmastrees',
connectionLimit: 5,
});
async function asyncFunction() {
let conn;
try {
conn = await pool.getConnection();
const rows = await conn.query("SELECT * from bäume");
console.log(rows); //[ {val: 1}, meta: ... ]
} catch (err) {
throw err;
} finally {
if (conn) return conn.end();
}
}
But when executing the file (node app), I get an error message after a few seconds
Error: connect ECONNREFUSED 127.0.0.1:3306
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16)
From event:

}
So I searched for help and after 2 hours I literally found only one Idea. I added this line of code to my connection...
port: '/var/run/mysqld/mysqld.sock'
I tryed again to use node app, but this time I didn't get an error message, it is loading forever and nothing happens.
I would be so grateful for any help...
So I found the solution to my problem.
I checked if my MariaDB Service is even running and no it wasn't ^^
I'm trying to put in production a site I made with Angular and Express/Sequelize, but always have Sequelize errors :
It works perfectly fine in local with WAMP, I can reach my local database and it's all good.
When I'm trying to use my OVH database (that I got with my hosting plan), I have the following errors :

I don't understand because I've always used the same config, it works fine when I'm using a PHP PDO object on other projects for example. It doesn't work either on my OVH VPS, where I'm getting connection refused error (even if I had to look at all the tutorials on the net), but that's another problem.
Here is my db.config.js :
module.exports = {
HOST: "dodobwtdodob.mysql.db",
USER: "dodobwtdodob",
PASSWORD: "secretpassword",
DB: "dodobwtdodob",
dialect: "mysql",
pool: {
max: 5,
min: 0,
acquire: 30000,
idle: 10000
},
port:3306
};
And here a part of my index.js :
const dbConfig = require("../config/db.config.js");
const Sequelize = require("sequelize");
const sequelize = new Sequelize(dbConfig.DB, dbConfig.USER, dbConfig.PASSWORD, {
host: dbConfig.HOST,
dialect: dbConfig.dialect,
port: dbConfig.port,
pool: {
max: dbConfig.pool.max,
min: dbConfig.pool.min,
acquire: dbConfig.pool.acquire,
idle: dbConfig.pool.idle
}
});
Please change hostname "dodobwtdodob.mysql.db" to ipAddress(host address).
I have vpn access, so i can ssh to server by following command from terminal
ssh qa-trinath01.my-qa
Its working fine from terminal.
But from nodejs, its not working. my code is
var express = require("express");
var app = express();
var node_ssh = require('node-ssh')
var
ssh = new node_ssh()
ssh.connect({
host: 'qa-trinath01.my-qa',
username: 'tanantham',
port: 27017,
privateKey: '/Users/tanantham/.ssh/id_rsa'
}).then(function() {
console.error('Success: ');
}).catch((error) => {
console.error('ERROR: ', error);
});;
app.listen(3001);
I am getting output as
ERROR: { Error: getaddrinfo ENOTFOUND qa-trinath01.my-qa qa-trinath01.my-qa:27017
at errnoException (dns.js:50:10)

hostname: 'qa-trinath01.my-qa',
host: 'qa-trinath01.my-qa',

level: 'client-socket' }
Can some one suggest the nodejs code to connect to ssh, i have only ssh key and ssh server name details.
ssh key -> /Users/tanantham/.ssh/id_rsa
server name -> qa-trinath01.my-qa
Have you tried to replace 'privateKey' with 'password' and enter your password.
It's probably not the most secure but it normally works.
Unless you have to use your private key from id-rsa
ssh = new node_ssh()
ssh.connect({
host: 'qa-trinath01.my-qa',
username: 'tanantham',
port: 27017,
password: 'YourPasswordHere'
}).then(function() {
console.error('Success: ');
}).catch((error) => {
console.error('ERROR: ', error);
});;
app.listen(3001);
I am trying to make a simple connection between my nodejs server and my mysql db (using Microsoft SQL server manager studio v14), below is my code and the error message appearing in my console window.
here is my code:
var express = require('express');
var app = express();
var sql = require("mssql");
app.get('/', function (req, res) {
// config for your database
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX'
};
// connect to your database
sql.connect(config, function (err) {
if (err) console.log(err);
// create Request object
var request = new sql.Request();
// query to the database and get the records
request.query('select * from Schools', function (err, recordset) {
if (err) console.log(err)
// send records as a response
res.send(recordset);
});
});
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
The error I am getting looks like this:
Server is running..

I am rather new at this particularly with dealing with databases. Can someone explain what the error means?
Add this line to the config:
options: {
encrypt: false
}
It will finally look like:
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX' ,
options: {
encrypt: false
}
};
try to put encrypt: false in your config{}, it will work.
your error:
ConnectionError: Failed to connect to localhost:1433 - Could not
connect (sequence)
My problem was resolved by adding port
var config = {
user: 'superadmin',
password: '***',
server: 'localhost',
database: 'XXX',
port: '',
};
I'm trying to call freecodecamp api #url https://forum.freecodecamp.org/c/getting-a-developer-job.json?
I am doing some analysis on the data, but when I call this service using 'request' npm package I am getting ssl error as follows:
error { Error: write EPROTO 140735782093632:error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure:../deps/openssl/openssl/ssl/s3_pkt.c:1500:SSL alert number 40

at _errnoException (util.js:1022:11)
at WriteWrap.afterWrite [as oncomplete] (net.js:867:14) code: 'EPROTO', errno: 'EPROTO', syscall: 'write' }
Can somebody let me know what the issue is? A wget call pulls the data when provided with --ca-certificate option, also the webservice is giving data to postman without any certificate.
Here is my code:
import request from 'request';
import fs from 'fs';
const BASE_URL = 'forum.freecodecamp.org/c/getting-a-developer-job.json?no_subcategories=false&page=1';
request.get(BASE_URL, {
port: 443,
agentOptions: {
ciphers: 'ALL',
ca: fs.readFileSync('./mycertfile.pem'),
secureProtocol: 'TLSv1_2_method'
},
strictSSL: false
})
.on('response', (response) => {
console.log('Response is ', response);
}).on('error', (err) => {
console.log('error', err);
});
I see no problems there except URI http:// is absent, in my environment i have node v10.5.0, and the slightly modified version of your script works well:
const request = require('request')
const BASE_URL = 'https://forum.freecodecamp.org/c/getting-a-developer-job.json?no_subcategories=false&page=1'
request.get(BASE_URL, { json: true }, (err, res, body) => {
if (err) throw('error', err);
console.log('JSON object is => ', body);
})
outputs to console:
JSON object is => { users:
[ { id: 117390,
username: 'anthony2025',
....
