Dropbox Community ModeratorThe api.dropboxapi.com host is currently being served with a valid certificate, so it's not clear why your client isn't trusting it. (Is there any security software, e.g., firewall, or a proxy that may be intefering?)
In any case, the /2/files/list_folder endpoint does need to be called on the Dropbox API servers, for which either of these host names are valid:
- api.dropbox.com
- api.dropboxapi.com
The /2/files/download endpoint does need to be called on the Dropbox API content servers, for which either of these host names are valid:
- api-content.dropbox.com
- content.dropboxapi.com
(Note that at the end of your post you mentioned "content.dropbox.com isn't available in v2". That is true in that "content.dropbox.com" is not a valid host name, but "content.dropboxapi.com" is valid and does serve API v2.)
Thank you for your detailed answer. Based on this, I was able to track down the bug, which was indeed a wrong content url.
Thank you, issue solved.
