Why doesn't fsspec see files via HTTPS on this Open Storage Network bucket?

[rsignell-usgs]

import fsspec
fs = fsspec.filesystem('https')
fs.ls('https://ncsa.osn.xsede.org/Pangeo')

returns []

But if I point my web browser at that URL, I see:

"

I guess that's because that's not a file, but a service, right?

Doh! This is really an S3-compatible Open Storage Network Bucket, so this is the way to explore files with fsspec:

To answer the original question, in case people are interested: the http implementation does ls by loading the given URL, and looking for HTTP links with names that are like "{original_url}/...". They keys in that XML do not match that pattern, and are not HTTP links anyway.
