title: Searchkick with ElasticSearch returns "Faraday::ConnectionFailed: execution expired"
body: <p>I've been using the <a href="https://github.com/ankane/searchkick" rel="noreferrer">searchkick</a> gem with elasticsearch with no problems on a Rails 4.2.0 application. I have a single Video model using searchkick.</p>
  
  <p>For some reason <code>rake searchkick:reindex:all</code> is now failing consistently with:</p>
  
  <blockquote>
    <p>Reindexing Video... rake aborted! Faraday::ConnectionFailed: execution
    expired</p>
  </blockquote>
  
  <p>I originally installed elasticsearch via <code>brew install elasticsearch</code>, which returns:</p>
  
  <blockquote>
    <p>Warning: elasticsearch-1.3.4 already installed</p>
  </blockquote>
  
  <p>Is it likely that my elasticsearch installation/database has become corrupted? If so, what is the best way to refresh it?</p>
  
  <p>As per <a href="https://www.elastic.co/guide/en/elasticsearch/reference/1.4/indices-delete-index.html" rel="noreferrer">https://www.elastic.co/guide/en/elasticsearch/reference/1.4/indices-delete-index.html</a> I tried <code>curl -XDELETE 'http://localhost:9200/_all'</code> but this doesn't resolve the error.</p>
  
  <p>This problem occurs on my Mac, as well as Elastic Beanstalk when I deploy this code to AWS (both were previously working correctly).</p>
