Answer 1

rubber:setup_local_aliases seems to be the source of the problem so perhaps you haven't set something correctly in your rubber.yml file. Forgot to set domain name perhaps? Moreover I tried deploying yesterday with complete_unicorn_nginx_postgresql and HAproxy was having some issues in the port binding with nginx_unicorn, so be careful with those.
