title: Can't connect to scrapyd api
body: <p>I'm trying to use the scrapyd service to schedule a spider. I'm on mac os 10.9.5. I start the service by running 'Scrapyd', it's running fine and I can navigate to the interface on <a href="http://localhost:6800" rel="nofollow">http://localhost:6800</a>. </p>
  
  <p>But when I try to use the api, for example: curl <a href="http://localhost:6800/schedule.json" rel="nofollow">http://localhost:6800/schedule.json</a> -d project=myproject -d spider=somespider </p>
  
  <p>I get the following error:</p>
  
  <p>(7) Failed to connect to localhost port 6800: Connection refused</p>
  
  <p>The spider runs fine using 'scrapy crawl MySpider'.</p>
  
  <p>All help much appreciated! </p>
