Not being able to connect to azure redis service

I have a webapp deployed in azure, and I´ve also configured a azure redis cache, but I am not being able to make my cache work. My nextjs frontend app is hosted in vercel.

This is my redis client in my nodejs app:

const redis = require("redis");
const dotenv = require('dotenv');

dotenv.config({ path: './.env' });

// Variables de entorno para la caché
const cacheHostName = process.env.AZURE_CACHE_FOR_REDIS_HOST_NAME;
const cachePassword = process.env.AZURE_CACHE_FOR_REDIS_ACCESS_KEY;

if (!cacheHostName) throw new Error("AZURE_CACHE_FOR_REDIS_HOST_NAME is empty");
if (!cachePassword) throw new Error("AZURE_CACHE_FOR_REDIS_ACCESS_KEY is empty");

exports.connect = async () => {
  let client;

  if (process.env.NODE_ENV === 'production') {
    client = redis.createClient({
      // Configuración de Redis para TLS en producción
      url: `redis://${cachePassword}@${cacheHostName}:6380`,
      tls: {
        rejectUnauthorized: true // Asegúrate de que este valor sea verdadero para requerir SSL
      }
    });
  } else {
    // Configuración local de Redis para pruebas
    client = redis.createClient({
      host: 'localhost',
      port: 6379
    });
  }

  client.on('connect', () => {
    console.log('Cliente Redis conectado al servidor');
  });

  client.on('error', (err) => {
    console.error('El cliente Redis no pudo conectarse al servidor:', err);
  });

  client.on('end', () => {
    console.log('La conexión del cliente Redis se cerró');
  });

  await client.connect();

  return client;
};

My SSL port in the redis service is disabled and my SSL port is 6380, and the TLS version is 1.2

Everytime I make a request through postman or through my hosted app, the request stays in an infinite Sending request....

I have also tried with rejectUnauthorized: false and no changes were shown.

It seems that my redis client is connecting and failing connection in an inifinite loop:

    at TCP.onStreamRead (node:internal/stream_base_commons:218:20) {

This is how I am handling redis in my controller method.

const { User } = require('../models');
const asyncHandler = require('../middlewares/async');
const { connect } = require('../redis/redis')

//@route    GET api/users/
//@desc     Get all users
//@access   Private
exports.getUsers = asyncHandler(async (req, res, next) => {
   const redis = await connect();

   const key = 'users';
   const redisUsers = await redis.get(key);

   if( redisUsers ) {
      console.log('Users From Redis')
      return res.status(200).json({
         success: true,
         data: JSON.parse(redisUsers)
      })
   }
      
   console.log('Users From DB')
   const users = await User.findAll();
   await redis.set(key, JSON.stringify(users));
   return res.status(200).json({
      success: true,
      data: users
   })
});

In my local environment if I connect to redis to port 6379 and to host localhost it works fine, but as soon as I try connecting to the service of redis in azure it fails.

In the network tab of the browser when I make a request going to a view that displays a list of users I get the request for long time with no status code and finally I get a CORS error but CORS is enabled from azure. Finally the response from my frontend is of type text/x-component instead of json.

Note: this error only occurs in requests that include redis in my server
