If you encounter any playback problem with your radio web player, it's probably because your stream still uses SHOUTcast version 1. What you will experiment is that the radio is not playing even when you press the play button.
Browsers that no longer supports SHOUTcast 1:
- Chrome 55+
- Safari (macOS Sierra+)
To fix the issue, you should upgrade to SHOUTcast 2.
