Well, shoot, this isn’t something I run into everyday here 😕. If you write in to our support team, one of our agents can dig in with you a bit further, and get your query to the right desk for assistance!
@Lechucico To clarify, are you getting the 400 on guest1:8080/DropboxRest/app/dropbox/finish, or from Dropbox itself? Please share full Dropbox URL if that's where you're getting the error, as well as the full error message.
