The link to the dropbox file does not seem to work. It shows the following error message:
"Can't access"
"The owner hasn't granted you access"

I am able to access the file via Dropbox. However, I am not able to access the same file via the dropbox-file link attached to Trello.
Anyone who can help me out with this issue?
Some other point that might be relevant:
- I have only a viewing-access to this file (in Dropbox)
- I have a Trello Business account and a Dropbox Plus Account
- I am able to attach a link to a dropbox file and open this link myself.
