Node JS TLS server and client aren’t working correctly

Recently I’ve been trying to make a basic TLC server and client to maybe put on a Rasperry PI. I found an example on github and i modified it so its up to date. My issue is that Node JS keeps saying unable to verify the first certificate Even though i generated a new one.

note the certificates and keys are self signed.

Here is my code, I have not the slightest clue as to why its failing because when I set ServerOptions As the client options, it just logs Unsecure connection.

Server.js

'use strict';

const tls = require('tls');
const fs = require('fs');
const util = require('util');
const events = require('events');
const port = 4170;

const ServerOptions = {
    key: fs.readFileSync('agent1-key.pem'),
    cert: fs.readFileSync('agent1-cert.pem'),
    ca: fs.readFileSync('root-cert.pem'), // authority chain for the clients
    requestCert: true,
    rejectUnauthorized: false
};

var server = tls.createServer(ServerOptions, (socket) => {
  socket.write('welcome!\n');
  socket.setEncoding('utf8');
  socket.pipe(socket);
})

.on('connection', function(c) {
    console.log('Unsecure connection');
})

.on('secureConnect', function (c) {
    // c.authorized will be true if the client cert presented validates with our CA
    console.log('secure connection\n client authorization Status:', c);
})

.listen(port, function() {
    console.log('server listening on port' + port + '\n');
});`

Client.js

const tls = require('tls');
const fs = require('fs');
const util = require('util');
const events = require('events');
const port = 4170;

const ClientOptions = {
  key: fs.readFileSync('agent2-key.pem'),
  cert: fs.readFileSync('agent2-cert.pem'),
  ca: fs.readFileSync('root-cert.pem')
};

const socket = tls.connect(port, ClientOptions, () => {
      console.log('client connected', socket.authorized ? 'authorized' : 'unauthorized');
      process.stdin.pipe(socket);
      process.stdin.resume();
    });
    socket.setEncoding('utf8');
    socket.on('data', (data) => {
      console.log(data);
    });
    socket.on('end', () => {
      server.close();
    });

So as you probably saw, there is the ca1-cert.pem, agent1-cert.pem, agent2-cert.pem, agent1-key.pem, and agent2-key.pem. Those are the certificates.

Each of the cert files have the beginning and ending

-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----

And each of the key files have the beginning and ending

-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----

In addition to that, I’m wondering how secure this is because my initial plan is to use this as a login/database server or something that cant be easily hacked into.

Thank you.
