title: Nginx+Tomcat - 504 timeout
body: <p>We receive a lot request on nginx some of them werent reached tomcat we just got Error 504 timeout on Nginx but nothing on Tomcat</p>
  
  <p>Our configuration
  Nginx routes traffic to virtual server (Windows Server) where is installed tomcat 7</p>
  
  <p>We cant figure out where is problem
  I thought if it is problem with tomcat we should see at least request from nginx on tomcat logs</p>
