title: Sidekiq jobs stuck in queue on Heroku
body: <p>I have a Sidekiq worker functioning well locally, but when deployed to Heroku the jobs get stuck in the queue.  I am using Redis-to-go nano and have it up and running, and I have scaled the worker to 1 on Heroku and can see that it is up.  I am just using the default queue -- nothing custom or fancy.  Here is my code: </p>
  
  <p>config/unicorn.rb:</p>
  
  <pre><code>Sidekiq.configure_client do |config|
    config.redis = { size: 1, namespace: 'sidekiq' }
  end
  </code></pre>
  
  <p>config/initializers/redis.rb</p>
  
  <pre><code>uri = URI.parse(ENV["REDISTOGO_URL"] || "redis://localhost:6379")
  REDIS = Redis.new(:url =&gt; ENV['REDISTOGO_URL'])
  </code></pre>
  
  <p>Procfile</p>
  
  <pre><code>web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
  worker: bundle exec sidekiq -c 5 -v -q default
  </code></pre>
  
  <p>I can see the job in the queue but it is not processing like it does locally.  Any advice is much appreciated - thanks!</p>
