Why won't files from web galleries download anymore?

I have been sharing folders on my creative cloud in order for clients to download images after shoots.  I just got an email from two of them saying they couldn't download any more.  One of the galleries I was able to take offline and put back on with success.  The other one I just found out about and I am traveling.  It's a large gallery (4+gigs)  so I cannot do this remotely or quickly.  Is there a way to fix this?  I am not over my storage limit on CC as I thought that could be an issue.
