What did you try yet?

reinstall all
change node version to 14.7.3
change mineflayer version to 4.5.0
Switch from LINUX to WINDOWS

Your current code

const mineflayer = require('mineflayer')
const config = require('./config.json')

const bot = mineflayer.createBot({
  host: config.host2,
  username: config.username,
  password: config.password,
  port: Number(config.port2),
  version: config.version,
  auth: config.auth,
  disableChatSigning: true
})


bot.on('chat', (username, message) => {
  console.log(message)
  if (username === bot.username) return
  bot.chat(message)
})

// bot.on('message', (message) => {
//   console.log(message)
// })

// Log errors and kick reasons:
bot.on('kicked', console.log)
bot.on('error', console.log)

Expected behavior

echo message
