 * Hi [@jrovirag](https://wordpress.org/support/users/jrovirag/)
    Please try to 
   delete and create the dropbox again by following our official guide in here: 
   [https://backwpup.com/docs/backup-wordpress-to-dropbox/](https://backwpup.com/docs/backup-wordpress-to-dropbox/)
   Is that helps?

    since we haven’t 
   heard back from you, I’m going to mark it as resolved. If you’re still having
   problems, feel free to let us know ;),
