Can't create Docker network : <p>I've been able to start my Docker application without a problem but suddenly I get this error:</p>

<blockquote>
  <p>failed to parse pool request for address space "LocalDefault" pool ""
  subpool "": could not find an available, non-overlapping IPv4 address
  pool among the defaults to assign to the network</p>
</blockquote>

<p>I'm running Docker 1.12.6.</p>

<p>How do I fix this?</p>
