Javascript 在线聊天应用程序错误-加载资源失败：net:：ERR\u SSL\u PROTOCOL\u错误

因此，我正在制作一个在线聊天应用程序，当我尝试连接时，我收到了这条消息。我确信代码是正确的，但我认为这是电脑或防火墙上的设置阻止了我的连接。有人能帮忙吗

**server.js**- const io = require('socket.io')(3000)

io.on('connection', socket => {
socket.emit('chat-message', 'Hello World')
}) 

**script.js** - const socket = io('https://localhost:3000')

socket.on('chat-message', data => {
console.log(data)
}) 

**package.json** - {
