rails + carrierwave + fog + S3 socket error

I'm having this problem trying to use S3 services with fog and the Jquery File Upload (https://github.com/blueimp/jQuery-File-Upload) The error ``` Excon::Errors::SocketError (getaddrinfo: nodename nor servname provided, or not known (SocketError)): ``` This occur when i try to call "save" method in the controller. I'm setting carrierwave as follow: config/initializers/carrierwave.rb ``` CarrierWave.configure do |config| config.fog_credentials = { :provider => 'AWS', :aws_access_key_id => 'access_key_here', :aws_secret_access_key => 'secret_key_here', :region => 'eu-east-1' } config.fog_directory = 'folder_name_here' config.fog_public = false config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} config.storage = :fog end ``` and my uploader just the "config.storage :fog" and the "store_dir" Now, I have created my bucket already. Am i missing some configuration? It doesn't even work on my dev environment. Please any help. Thanks in advance.
