title: "cURL error 77: error setting certificate verify locations" for no obvious reason
body: <p>I am running PHP 7.1 on Windows and seeing a weird behavior.  When using cURL to make API calls, everything seems to work for a little bit.  After some random interval, the calls start failing with this error.</p>
  
  <p><code>cURL error 77: error setting certificate verify locations: CAfile: c:\&lt;path intentionally removed&gt;\cacert.pem CApath: none (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)</code></p>
  
  <p>Restarting Apache seems to fix the issue. Then after some random time, it starts showing up again for no obvious reason.  Does anyone know what might be going on here?</p>
