title: sidekiq getaddrinfo error(No address)
body: <p>I'm trying to run sidekiq but I'm getting this error:</p>
  
  <p>getaddrinfo: No address associated with hostname</p>
  
  <p>this is what I have in my sidekiq file (configinitializers):</p>
  
  <pre><code>Sidekiq.configure_server do |config|
  config.redis = { url: 'redis://Policia9@host:6379'}
  end
  
  Sidekiq.configure_client do |config|
  config.redis = { url: 'redis://Policia9@host:6379'}
  end
  </code></pre>
  
  <p>Seems I simply used the non-existent host given in the docu, of course I need to put my own host or ip in there,but I don't know where to find the file.</p>
