title: crawl https pages with crawler4j
body: <p>For months now we used crawler4j to crawl a https site. Suddenly, since last friday, we're not  able to crawl the very same https site. Has something changed in the https-protocol?
  The site is <a href="https://enot.publicprocurement.be/enot-war/home.do" rel="nofollow">https://enot.publicprocurement.be/enot-war/home.do</a></p>
  
  <p>As a test, just try to grab the title: Welkom op het platform e-Notification</p>
  
  <p>Any help is much appreciated.</p>
