title: Hyperledger REST Server Angular Web App getting could not connect to REST server outside localhost
body: <p>I'm following the great Hyperledger Composer tutorials <a href="https://hyperledger.github.io/composer/tutorials/developer-guide.html" rel="nofollow noreferrer">here</a> to getting started. I've managed to get everything running, including the REST Server and the Skeleton Angular web app on top of it. </p>
  
  <p>Problem arise when I try to use the application outside of localhost. I can access the REST Server on port 3000 and interact with it (adding, removing, uppdating). I can also access the application (port 4200), but when I try to interact with it I get the following: </p>
  
  <pre><code>Error: Could not connect to REST server. Please check your configuration details
  </code></pre>
  
  <p>I've tried to update the angular-cli to support my current startup script as: <code>ng serve --host 0.0.0.0 --disable-host-check --public my.ip.address.here:4200</code> it seems to be working because I get the security warning about disabling host check but it's not solving the problem.</p>
  
  <p>Any suggestions would be much appreciated. Thank you in advance. </p>
