PHP app - not all requests being received?

Hi,

We’re running the PHPMyVisities PHP app on IIS 6.0 behind NGINX to track visitor stats for an ASP.NET web application also running behind the same NGINX.

We moved to this approach two days ago from having the PHP app just runing on IIS 6.0 without NGINX in front.

Since this move our visitor stats have halved so we’re trying to understand whether it was the move behind NGINX that has ‘somehow’ caused it. Could NGINX somehow be not letting all the PHP requests through therefore some of our web hits aren’t being registered?

Many thanks for any help you can provide.
