title: Facebook's Get Url Like count API has limit?
body: <p>I use graph API to get like count of specified URL:</p>
  
  <p><strong>https://graph.facebook.com/?ids=[URL]</strong></p>
  
  <p>This API can works on test environment, but we I deploy it to production environment, this API returns error: <strong>No connection could be made because the target machine actively refused it.</strong></p>
  
  <p>Is the API has any request limits?
  Or, how can I resolve this issue?</p>
  
  <p>Thanks for any answer.</p>
