"Internal error" when trying to restore files

Sorry to see you're having an issue restoring your files, Sylvain255.

Does this happen when you're using Dropbox Rewind, or when you restore your files from the deleted files page?

Have you tried from a different browser or a private browsing/incognito window?

Let me know what you find.

it is done on firefox, chrome even if I am in a private window

it is Dropbox Rewind

Are you seeing the below (screenshot) when using Rewind via Dropbox.com website?

If yes, it's one of many  frustrating Dropbox problems. The rewind feature seems to fail more frequently if there was a lot of data traffic just before the date which you're restoring.  My work around was to wait for a few days and then restore individual folders instead of a full account restoration.  

yes it is but is the Dropbox support can restore it for me ?

ok thank you

and do we receive a mail when the restoration by support is finished ?

Just for info .... Don't empty/permanently delete  your "Deleted Files" on dropbox.com or you will not be able to Rewind your account ....

"and do we receive a mail when the restoration by support is finished ?"

I'm not sure if they will offer a status update but you should see all your files return back to normal .... Try using the "support chat" and you can ask that question 😉

the chat doesn't work for me, when I click in the button nothing happens
