Get tarted - Part 5 - Hello World!

Hi everyone.
I copied the index.html file on my Synology server and when I access it through the local address (192.168…) it works fine, but when I access it through https I have no effects (WebGL). See images.
Sorry I’m a beginner in the web world.

What’s the URL in the address bar where you see problems?

Look in browser dev tools console for errors.
