Videos in Epicgames Web Courses has been blocked by CORS policy

I got message like this from Chrome:
Access to XMLHttpRequest at ‘https://assetseg2-1251447533.file.myqcloud.com/d052f82e-3734-4914-a961-8ce29135079e/init_4.mp4’ from origin ‘https://dev.epicgames.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Please fix it!
