Where or how publish the file for rss feed Product landing page

I try put the rss feed to Product landing page

The appvisor and jQuery probably need the direct link with end file.rss.
In google drive directlink do not working.
As solution because the ftp is payed I chose put down the file in my azure website as file., because similar I use the Images folder. as here http://commacheck.azurewebsites.net/images/grafy2017googleanalytics.GIF

so I similar put the file commarss.rss in new folder export
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
locally I get:

Most likely causes:

    It is possible that a handler mapping is missing. By default, the static file handler processes all content.
    The feature you are trying to use may not be installed.
    The appropriate MIME map is not enabled for the Web site or application. (Warning: Do not create a MIME map for content that users should not download, such as .ASPX pages or .config files.)
    If ASP.NET is not installed.
