Why is it not connecting to wss?

Question

Nginx

nginx

server {
    charset utf-8;
    client_max_body_size 128M;
    listen 80;
    listen 443 default ssl;
    ssl_certificate         /etc/nginx/ssl/cert.pem;
    ssl_certificate_key     /etc/nginx/ssl/cert.key;
    server_name url;

nodejs

const https = require('https'),
    fs = require('fs'),
    WebSocket = require('ws'),
    server = https.createServer({
     ssl: true,
                 cert: fs.readFileSync('/etc/nginx/ssl/cert.pem'),
                 key: fs.readFileSync('/etc/nginx/ssl/cert.key'),
                 port: 2052,
}),

nginx is under cloudflare
Gives an error Error in connection establishment: net::ERR_SSL_PROTOCOL_ERROR

Answer 1

Decide if you have this server for HTTP or HTTPS.
For nginx, encryption, IMHO, is superfluous.
