media upload nginx Multi-Site .zip files = 404 error

Hi Guys,
I am having a odd issue.

I add the file type .zip I am able to upload the file as admin in the man site and I can access the file.

When I upload the file as a multi site user the file uploads I can see the file in the media manager.
I can confirm that the file exists on the server with the same permissions as all the other files.

But when I click to download the file I get a nginx 404 error.
If I upload a graphic it works AOK I can download it no problem

I am guessing it is my nginx conf
