Sidekiq 5 does not work with AWS ELB and 5 api rails

Ruby version: 2.3.1

Sidekiq / Pro / Enterprise Version (s): 5.0

Rails: 5.0.2

I followed this tutorial so I could use sidekiq to send emails in my rails api app. The app is published on AWS ElasticBeanstalk with Puma.

When a user signs up, they should receive an email (via the device). The error is not displayed, no log is generated in sidekiq.log. I don't know what's going on, the letters just don't get delivered.

/ Devise_async.rb initializers

Devise::Async.setup do |config|
  config.enabled = true
  config.backend = :sidekiq
  config.queue   = :default
end

      

        
        
        
      

    

Initializers / sidekiq.rb

rails_root = Rails.root || File.dirname(__FILE__) + '/../..'
rails_env = Rails.env || 'development'
redis_config = YAML.load_file(rails_root.to_s + '/config/redis.yml')
redis_config.merge! redis_config.fetch(Rails.env, {})
redis_config.symbolize_keys!
Sidekiq.configure_server do |config|
  config.redis = { url: "redis://#{redis_config[:host]}:#{redis_config[:port]}/12" }
end
Sidekiq.configure_client do |config|
  config.redis = { url: "redis://#{redis_config[:host]}:#{redis_config[:port]}/12" }
end

It works fine on local machine.

Do you have any ideas?
