You can see that the first one http://example.com/ is 301 redirected to http://www.example.com/. And that is what you want as your preferred url is http://www.example.com/.

When you requested http://www.example.com/, you are getting a 200 OK response and that is perfect.

So the issue isn't at your end at all.
