By the way, your CDN version of this sample does also not work but is throwing this error:

browser console log:  
sockjs.js:1606 GET [http://localhost:9999/sockjs-node/info?t=1587708040981](http://localhost:9999/sockjs-node/info?t=1587708040981) net::ERR\_CONNECTION\_REFUSED

node.js:  
[2020-04-24T06:03:20.294Z] “GET /sockjs-node/info?t=1587708199986” Error (404): “Not found”
