Presigned url : votre connexion à ce site n'est pas sécurisée

Hi Tomzr,

There are no additional actions that need to be taken when sending a request to /files/get_temporary_link to generate a temporary link.

Since you have confirmed only some users get the error message, it could very well be security software blocking connection to the domain contained in the link.

Feel free to reference the following article for a list of official domains used by Dropbox: https://help.dropbox.com/security/official-domains

I hope you find this information helpful!
