title: Unable to access full web service in Ubuntu virtualbox
body: <p>I got a Win10 host system and a virtualbox ubuntu 16.04 guest system.
  The network is bridged and disabled the firewall in the ubuntu system.
  I installed a Openstreetmap-Server (osm) after this:
  <a href="https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04" rel="nofollow noreferrer">https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04</a></p>
  
  <p>It uses apache2 to serve the tiles over mod_tile. The rendering is fine.</p>
  
  <p>The webfront ist umap (a package with leaflet) after this tutorial.</p>
  
  <p><a href="https://umap-project.readthedocs.io/en/latest/ubuntu/" rel="nofollow noreferrer">https://umap-project.readthedocs.io/en/latest/ubuntu/</a></p>
  
  <p>The webfront runs over nginx and uwsgi.</p>
  
  <p>In the Ubuntu guest system all is working fine.
  I can access with Firefox the website and the rendering is fine.</p>
  
  <p>When I want to access the website from the Win10 host system, the "normal" website ist fine, too. The part where the map should be is grey and gets not rendered. Why the access from the host system is only half working?</p>
  
  <p>I cannot get it working outside the virtualbox, but why :(</p>
