CORS enabled on Icecast Server but error about icecast-metadata-js HOT 5 CLOSED

Your Icecast CORS policy is set up correctly. Are you serving your website using HTTPS? Browsers will block requests to HTTP resources (your Icecast server) if they are being referenced from a HTTPS origin. Disabling the Chrome web security is likely what is allowing these requests to succeed. The simplest way to fix this would be to enable HTTPS on your Icecast server: https://icecast.org/docs/icecast-2.4.1/config-file.html#path

from icecast-metadata-js.

Serving website over http and https, in this case accessing over http.
If I access website over https and stream over http it says
icecast-metadata-player-0.0.3.min.js:20 Mixed Content: The page at 'https://websiteurl' was loaded over HTTPS, but requested an insecure resource 'http://streamurl'. This request has been blocked; the content must be served over HTTPS.

I'm doing various tests... (all failed until now)

from icecast-metadata-js.

Since you're serving on both http and https, this could be happening when you switch over to http: https://superuser.com/questions/565409/how-to-stop-an-automatic-redirect-from-http-to-https-in-chrome

Quite sure i'm accessing it over http, it says "not secure" and if I copy and paste the url it's "http://"

Reinstalled all the stream package (icecast, butt, etc) in another computer in another network just to test but same results.

from icecast-metadata-js.

Analyzed some of the stream found on your demo page and I found a solution: All the demo servers i tried were "Icecast 2.4.0-kh*", in fact the only server which works for me is
Server: Icecast 2.4.0-kh15

Here is the CURL log:

Don't know why it's happening :(
