System upload not using s3 cdn url

I am using minio as a S3 gateway internal. However, when upload a image, it does not using the CDN url.

For example, uploading a avatar and it uses a internal IP instead of cdn url. This make the avatar fail to display.

Does the IP discourse presents as the CDN match the IP you’re using for Minio? Does the public DNS name for Minio have a certificate?

Yeah this is indeed the case, preview does not use CDN, hiding the S3 origin from clients is an unsupported setup atm, longer term I expect even more trouble when we support direct to s3 uploads

I also found out the images uploaded are allowed to view by public. If there are future updates on this, please do not set it if CDN is set. This is because it bypass the bucket policy to enforce all objects must go through CDN.
