Recent security measures from the most popular browsers will prevent streaming of unsecure radio streams through secure websites.
What does it mean?
This means that if your website is in HTTPS, also your radio stream needs to be available in HTTPS, otherwise you won’t be able to listen any music. This is not a player limitation, but a browser security feature.
There are many providers offering secure connection for your stream, so, if you plan on having your website under HTTPS, make sure your stream is accessible via HTTPS as well, and that it has a valid SSL certificate.
