title: Django manage.py command hangs
body: <p>What worked perfectly normally before, has just given up on me. When using any type of <code>manage.py</code> command like below, I see <code>Performing system checks...</code></p>
  
  <pre><code>python manage.py runserver 
  </code></pre>
  
  <p>or </p>
  
  <pre><code>python manage.py makemigrations
  </code></pre>
  
  <p>After about a 30-60 seconds of hanging, I then get:</p>
  
  <pre><code>System check identified no issues (0 silenced).
  </code></pre>
  
  <p>Which hangs and hangs and hangs...then after about 6 minutes, I see again the normal <code>Quit the server with CONTROL-C</code>
  To debug this issue, I even tried to comment out my apps and middleware, as well as shut down other applications on my PY and perform a reboot, still no change. What else do I need to look at with this? This seems far too long.</p>
