title: Docker not working with a VPN due to network issues
body: <p>For some reason my VPN (NordVPN) is interfering with Docker:</p>
  <pre class="lang-sh prettyprint-override"><code>make start
  docker-compose -f docker-compose/docker-compose.base.yml -f docker-compose/docker-compose.dev.yml up -d
  doCreating network &quot;docker-compose_default&quot; with the default driver
  ERROR: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network
  cmake: *** [Makefile:59: up_dev] Error 1
  </code></pre>
  <p>The issue seems to be to do with networking. I'm not sure how to troubleshoot it or fix it, though. After disabling my VPN and running <code>sudo systemctl restart docker</code>, Docker works fine.</p>
