Attaching a Alias for Cloudfront returns error

Hi Helpdesk,

I am able to see the CDN working with a CDN url attached screenshot confirms it.

But we alias the CDN alias then getting the following error saying encode at higher bit rate.

It is the same video nothing fancy here , a similar issue was raised and was asked to clear the CDN cache. Please suggest the change here.

Thanks,
