Dropbox Community ModeratorThanks for the report! Like in the other thread you linked to, this 504 error can be related to these operations taking a long time due to a large number of files and/or a large amount of file activity in the affected account(s). That can vary over time due to account activity and other such factors though. We'll look into it.
You may be able to workaround this issue by setting recursive=false on /2/files/list_folder so I recommend giving that a try (though that may require updating your implementation accordingly).
Turns out a subtle but reasonable change to Dropbox upload responses uncovered a bug in our prototype devices. That caused the lack of listed files and also caused a lot of retries, which probably triggered the 504s when I dumped the cursors and restarted the listing. I resurrected the cursors and listings work now. Thanks for investigating.
