Didn't get my pull request to work, so I send you the updated code: https://github.com/adon90/http-robtex-reverse-ip/blob/master/http-robtex-reverse-ip.nse

One reason why the script might not work for you at this moment is due to #708, i.e. nothing wrong with the script itself. Try patching http.lua and rerun the script.
