Rails 4 assets not loaded in production although work on local production server

My production server won't load any Rails assets. When I run

RAILS_ENV=production rails s 

I can see everything just fine. I even tried doing

RAILS_ENV=production bundle exec rake assets:precompile

Still no luck

Here is my production.rb

config.cache_classes = false
config.consider_all_requests_local       = false
config.action_controller.perform_caching = true
config.serve_static_files = false
config.assets.compress = false
config.assets.compile = true
config.assets.digest = false
config.eager_load = false
config.log_level = :debug
config.action_dispatch.x_sendfile_header = "X-Sendfile" # for Apache
config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for NGINX
ActiveSupport::XmlMini.backend='Nokogiri'

config.i18n.fallbacks = true

config.active_support.deprecation = :notify
