Backend i Node JS = HTTPS

Hej

Har skrivit en Node backend server med HTTPS enligt: Express.js HTTPS server

/* ==================================== Main server file ====================================
     Basic Server module */
const express = require('express');
const https = require('https');
const fs = require('fs');
let cors = require('cors');
const app = express();
app.use(express.json());
app.use(express.static('public'));
app.use(cors());

// Import usefull files
const textFile = require('./TextFile/ReadTextFile');

// The server information
const port = 3001;

// HTTPSercure server
const hskey = fs.readFileSync('fredrikDev-key.pem');
const hscert = fs.readFileSync('fredrikDev-cert.pem')
const serverOptions = {
    key: hskey,
    cert: hscert
  };
var httpsServer = https.createServer(serverOptions, app);
httpsServer.listen(port, () => console.log(`HTTPSserver is listening on port ${port}!`));

// Run default   
app.get('/GetText', (req, res) => {
    console.log('========================= ReadTxtFile ==========================================');
    // Collecting all textFiles into a object
    const sendTextOStr = {
        textMain: textFile.welcome(),
        services: textFile.services(),
        aboutMe: '',//textFile.abouteMe(),
    }
/*     const getSendingType = req.params.pageText;
    console.log("getSendingType", getSendingType)
 */    res.status(200).send(sendTextOStr//[getSendingType]
    );
})

När jag gör Axios anrop från min Frontend app måste jag godkänna certifikatet. Jag vill få upp sidan där jag kan godkänna innan appen kan hämta min data men nu är det lite krångligt.

Nu behöver jag öppna min backends url länk för att få upp sidan och godkänna certifikatet. Krångligt för den som inte är datorvan.
Det måste finna ett enklare sätt att göra t.ex. som ovan?

Mvh Fredrik

LetsEncrypt ser bra ut och verkar vara gratis

Har börjat att titta på det hur man går tillväga. Kan behöva lite vägledning under processen. Läser om steg 1 att avgöra om man gör med något skal program hmm?

Nu har jag installerat enligt instruktionerna och fått en csr fil med en key fil och installerat dessa enligt nedan:

// HTTPSercure server
const hskey = fs.readFileSync('0000_key-certbot.pem');
const hscert = fs.readFileSync('0000_csr-certbot.pem');
const serverOptions = {
    key: hskey,
    cert: hscert
  };
var httpsServer = https.createServer(serverOptions, app);
httpsServer.listen(port, () => console.log(`HTTPSserver is listening on port ${port}!`));

Får i konsolen:
[nodemon] restarting due to changes...
[nodemon] starting `node Server.js`
_tls_common.js:134
c.context.setCert(cert);
^

Vad göra eller är det fel på certet?

Terminalen då jag installerade certet, något har nog gått fel här?

IMPORTANT NOTES:
[0m - Your account credentials have been saved in your Certbot
configuration directory at C:\Certbot. You should make a secure
backup of this folder now. This configuration directory will also
contain certificates and private keys obtained by Certbot so making
regular backups of this folder is ideal.

Verkar som detta är felet?
