title: Symfony site robots.txt is not accessible
body: <p>I have a Symfony site hosted and recently Google webmaster tools notified that it cannot access robots.txt file. It is in the root but cannot be viewed in browser. It has produced this "New Index coverage issue detected for site <a href="http://www.example.com/" rel="nofollow noreferrer">http://www.example.com/</a>" error. When I checked I found out that Google cannot access robots.txt. I reuploaded a new sitemap.xml also.</p>
  
  <p>I changed the permission of robots.txt to 777, 775, 755, 644, 664 but still no luck. Also when I create test.txt it's contents are displayed in browser and it is accessible. How can I fix this?</p>
