socket.io.js error 403

[Вова Карташов]

Hello!

1) I installed EasyRTC on my VPS server s1.site.ru in the folder /home/s1.site.ru/public_html/

2) Run npm install in the /home/s1.site.ru/public_html folder and in the /home/s1.site.ru/public_htm/server_example folder

3) In the server.js file, replaced the port

webServer.listen (8080, function () {
    console.log ('listening on http: // localhost: 8080');
});

replaced by

webServer.listen (8082, function () {
    console.log ('listening on http: // localhost: 8082');
});

4) Run node server.js

Got:

info - EasyRTC: Starting EasyRTC Server (v1.1.1-beta) on Node (v8.10.0) undefined
debug - EasyRTC: Emitting event 'startup' undefined
debug - EasyRTC: Running func 'onStartup' undefined

Initiated

5) In the file demos/demo_audio_video_simple.html replaced

<script src = "/ socket.io/socket.io.js"> </script>

on the

<script src = "https://cdn.socket.io/socket.io-1.3.5.js"> </script>

without replace i have error: (404 not found) https://s1.site.ru/socket.io/socket.io.js 

6) In the browser I open https://s1.site.ru/demos/demo_audio_video_simple.html

In the first block, a video from my camera appears.Video and audio OK.

At the same time, a lot of errors appear in the browser console

Please tell me what could be the problem?
