title: unoconv not working while trying to convert. throws Error: Unable to connect or start own listener. Aborting
body: <p>I am trying to convert docx to pdf using <a href="https://github.com/dagwieers/unoconv"><code>unoconv</code></a>, but getting <code>Error: Unable to connect or start own listener. Aborting.</code> when I run <code>unoconv -f pdf 1234.docx</code>.</p>
  
  <p>So, there must be some listener. I then started the listener via <code>unoconv --listener</code>.<br>
  I tried <code>ps aux | grep soffice</code>, and found soffice.bin.</p>
  
  <p>So I tried  <code>unoconv -f pdf 1234.docx</code> again. It still gave me the same error:  <code>Error: Unable to connect or start own listener. Aborting.</code> </p>
  
  <p>What am I doing wrong here?</p>
