GLTF external

Hello, I am trying to add a gltf external that I have uploaded to dropbox but I get the following error message. I attach urls and files that I use because I don’t know why it didn’t work
URL gltf dropbox: scene.gltf
URL model in shapediver: ShapeDiver

The link from dropbox is missing a Content-Length header, which currently does not work for importing external files. We recommend using your own server or a more advanced hosting provide like AWS.
