How to make Websocket work on HTTPS?

Question

JavaScript

Hello.
Help, please, to understand. Studying the topic, I got confused.
Installed node.js, started the server. I connect via new WebSocket("ws://Server_IP:Port");
If SSL is disabled (that is, a site on http) - everything works fine.
If I enable SSL and change the connection to WebSocket("wss://IP_Server:Port") - I get an error.

Answer 1

Why is everyone trying to push SSL into the application? Use proxying through nginx and manage certificates there.
