Hi Team,
My setup is like this.
Used media cloud plug-in to offload the medias to an External S3 compatible storage, setup with Minio.
The files are offloaded OK, and all the medias will receive a new URL which is the URL of the S3 storage.
Then when I try to attach file from the media library in the WPDM package add interface, it will attach it, but when saving the package, it will not save the attachment. Nor when I try to insert file via URL.
See the screenshot here.

I had to upload the file from my server directory, from which I can see the file’s URL is a relative URL.
Is this because the WPDM do not accept this kind of setup?
Thanks
