Can you attach .Zip files to Resources tab for download?

Hi Guys,

So I have a client who wishes for downloadable .zip files types to be accessible through the course I am building for them.
I have attached PDF's & Word documents this way in the past but not a .zip file...
I attached it anyway and seemed to be working fine but when I uploaded and tested I was presented with an error message any time I clicked on the file to download.
I have attached my .story file and also a snippet of the error I receive when I try and download...
Strange as when I "Test Launch" the course through my LMS the download seems fine?...
I had originally hosted the zip folder online and used the trigger function to download the zip using the link url but my client wants the download hosted locally as the site is not a permanent option.
Any help/advice at all would be greatly appreciated!...
