I am encountering a 503 Service Unavailable error when trying to fetch files from Dropbox shared links programmatically using the fetch() API in my web application. The same link works fine in a browser, but fails when accessed through code. I have already converted the link to use dl=1 for direct downloads. This error happens even for small files, so I am unsure if the issue is due to missing or incorrect request headers, Dropbox blocking automated requests, temporary server downtime, or rate limiting for multiple downloads. Additionally, I would like to understand if there are any restrictions for large files or bandwidth limits that could cause this error. Could you provide guidance on the correct way to perform programmatic downloads from Dropbox without encountering these errors.
