404 error message on Facebook post

Question

I have a Dropbox Basic (free) account. I'm trying to post a Dropbox link on a Facebook group. The link is to a folder containing 205 photos totaling 836 MB. Before even posting, Dropbox presented a 404 Error message in the text I was about to post. I'm not attempting to sell the images. Why am I getting the 404 Error?

I tried posting the link again, and it successfully posted. So this one can be closed as unreproduceable.

Yes, the same link works for a friend I've shared it with, as well as from a private browsing session I created.

Thank you for looking into this.
