staticWeb throws 401 on all manifests

Each time I try to download a public file using the staticWeb middleware and the link provided in the container index list, I get a 401 Unauthorized error. Downloading the large file using the swift cli works every time however. Downloading any other files <5GB using the staticWeb listing works as well.

I've checked the _segments container and each of those objects are publicly accessible and I can download each of them independently. The problem seems to be with only the manifest links.

I'm not sure what else to check, but any help would be greatly appreciated.
