I'm not familiar with windows version of nginx .. but it's clear you have 
all the required modules.
If nginx is blocking something at least we know that the current 
configuration somewhat works.

To debug it is better to start with a minimal version.

First of all - which error is returned to the cloudflare server?
Is it 503 which would come from the limit_* modules or is it 403 which would 
come from an invalid referer?
