title: How to access a Plotly-Dash app server via LAN
body: <p>I have a Plotly-Dash app which is running perfectly fine under <code>localhost:8050</code> or <code>127.0.0.1:8050</code>.</p>
  <p>Question is: how can I access this app server from another computer in the same LAN?</p>
  <p>So far, I've tried to access <code>http://x.y.z.w/8050</code> with <code>x.y.z.w</code> being the LAN IP address of the server (ping goes ok). All I get is:</p>
  <blockquote>
  <pre><code>This site can’t be reached
  x.y.z.w refused to connect.
  </code></pre>
  </blockquote>
  <p>Same when I try to access the server from the server computer itself, but using LAN IP instead of <code>localhost</code> or <code>127.0.0.1</code>. ping is fine.</p>

  <p>On a note, the server computer (my laptop) is connected to the company network via VPN, but I don't think this would change anything, since that's the whole purpose of VPN. Then I remote desktop to a computer at the office and try to access back my server.</p>
