@obelich I'm not sure this is the right place to put your problem unless it has to do with the s3_host_name.

I'd check the installation instructions in the Readme (for example, do you realy need the latest paperclip version on git?), https://github.com/thoughtbot/paperclip#defaults, and http://www.rubydoc.info/gems/paperclip/Paperclip/Attachment.default_options
