Can't upload swf to https

My swf doesn’t appear on my site when uploading an html page with an swf file embedded in it. I am using a mac osx 10.4 and dreamweaver. I can actually see the file here:

But When I hit preview in browser, it takes me to:

and gives me this error:
Not Found

The requested URL /html/indexTestFlash.htm was not found on this server.

Can anybody help? Why does it add /html in the link? Why does my swf not appear?
