title: Laravel snappy returning Failed to load about:blank, with network status code 301 and http status code 0 - Protocol "about" is unknown Error
body: <p>I am using laravel snappy based on wkhtmltopdf, everything was ok, but now on server and local I am getting this error:</p>
  <blockquote>
  <p>Failed to load about:blank, with network status code 301 and http status code 0 - Protocol &quot;about&quot; is unknown Error.
  And</p>
  <p>Blocked access to file /var/www/app/public/css/app.css</p>
  </blockquote>
  <p>And no image is rendered in pdf.</p>
  <p>This is so strange and discouraging to always being debugging snappy.
  I do not understand the issue and do not know how to fix it.
  anyone can help me please?
  thanks</p>
