title: docker running splash container but localhost does not load (windows 10)
body: <p>I am following <a href="https://blog.scrapinghub.com/2015/03/02/handling-javascript-in-scrapy-with-splash/" rel="nofollow noreferrer">this tutorial</a> to use splash to help with scraping webpages.I installed Docker toolbox and did these two steps:</p>
  
  <pre><code>$ docker pull scrapinghub/splash
  $ docker run -p 5023:5023 -p 8050:8050 -p 8051:8051 scrapinghub/splash
  </code></pre>
  
  <p>I think it is running correctly, based on the prompted message in Docker window, which looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/J0IFa.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/J0IFa.jpg" alt="enter image description here"></a>  </p>
  
  <p>However, when I open the `localhost:8050' in a web browser, it says the localhost is not working.

  <p>What might have gone wrong in this case? Thanks!</p>
