title: Plone making second http request by itself
body: <p>I got a plone 5 project where I work, and my HD just died. I had to reinstall in a new one, which is fine, and everything is working properly, except the fact that, looking at the log, I realized that every time my backend makes a request, it requests twice, once in http, and another in https.</p>
  <p>Outside that, the GET type of requests works just fine, but the POST, PUT, DELETE types of request do not. They are built properly and should work, since when I push it to the development env, it works, but not on my localhost, they always receive an error 500.</p>
  <p>Looking at the logs of the API I was posting to (Java), it states null pointer exception, but doesn't say where (and the devs didn't want to look either, since it's my problem and not theirs).</p>
  <p>Does anyone have a idea on what is happening?</p>
