Compatibility with s3 presigned

I used s3fs as my storage provider, imce is compatible with s3fs when browse files. But when I select one file/image, its url is https://xxx.s3.com/a/b/c/d.png, without signature, so that access denied when accessing this link.

Meanwhile, as I selected one in imce, the href is the same link that also denied by s3 server.

How can I fix this problem? Is there any suggestion?

Thanks a lot!
