Offload s3 does not seem to work on subdomains

Hi,

Our WP admin is installed on https://admin.domain.com and the content is served on https://www.domain.com. They are 2 separate servers but they both share the same database server. When we upload images from admin.domain and publish it the images are uploaded to s3 and display without any errors but the same page on https://www.domain return 404.

Is it possible that the offload s3 works for one domain only?

Thanks
