Any ways to bypass CDN url check?

I’m trying to setup AWS Cloudfront CDN but there’s a issue:

cloudfront.net → mydomain.com request is blocked by hosting provider so I can’t get through CDN url check UI on “other CDN provider” settings page. (The hosting provider seems to block by Host header values like {Host : cloudfront.net} but I couldn’t easily change header values in AWS Cloudfront settings)

cloudfront.net → mydomain.com/something/image.jpg request is working fine so I assume CDN thing in total will work fine if “CDN url check” is done in some other way.
