我正在做一个Web应用程序，需要使用websockets，为此，我使用socket.io库， 在本地，一切正常，但是在使用Windows Server 2012上传到我的vps时，它不起作用 我收到以下错误
WebSocket connection to 'wss://mydomain:8082/socket.io/?EIO=3&transport=websocket' failed: WebSocket is closed before the connection is established.
WebSocket connection to 'wss://mydomain:8082/socket.io/?EIO=3&transport=websocket' failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT
因此我从Windows防火墙打开了端口8082，但是此端口用于协议通信 http，并且根据socket.io库，我需要通过https协议进行通信
由于我尝试通过此端口访问，因此出现以下错误
Mixed Content: The page at '<URL>' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint '<URL>'. This request has been blocked; the content must be served over HTTPS. polyfills.61502c8beb5856ffad29.js:1
Mixed Content: The page at 'https://mydomain/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://mydomain:8082/socket.io/?EIO=3&transport=polling&t=MTs8rqF'. This request has been blocked; the content must be served over HTTPS.
我的服务器来自Godaddy，我已经有ssl证书
我想知道如何打开通过https协议通信的端口，因为在尝试应用程序之前 在名为www.C9.io的测试服务器上，它可以正常工作，因为在此服务器上，端口已配置为可以通过使用http协议和https协议（两者）的url进行访问
感谢您的帮助，我对端口和服务器了解不多（这是我的第一个vps），非常感谢
