Your server/CDN hosting the media content must have a CORS configuration that allows the player domain to access the stream content’s domain (if they are different). This is a requirement for any HTML5 playback, not a Teltoo-specific requirement. Therefore, you would typically have this configuration already in place. However, for reference, if you have an origin server and a CDN, you will need to make sure both support the right CORS headers.
For wide-open CORS:
To open CORS, open to your website domain (e.g. yourtvstreamingwebsite.com):
Browsers accept only one CORS domain, so if your server returns this line several times, the browser’s AJAX requests will fail.
