Thank you for the response.  I made an assumption when attempting to access via my web browser over port 443 and I got a `404 Not Found`.  Therefore I assumed that the yum install would not work.  We also attempted to proxy this internally via Artifactory and still received a 404.  In an attempt to answer your question above, I attempted to install elasticsearch on my own Fedora machine.
