one question: do you shutdown all your app-servers or server-by-server, so
you still have 
a available application?

there ist the "down" option for you upstream-block to disable servers, even
if they are 
up, but using this in a dynamic process might get very frickling. 

whet do you use for iptables-rules? drop/reset? 

i'd debug your server/app-ports when the iptables-script enforces no
from my belly i wouldnt expect nginx to be the faulty chain link. 

what does your log tells you when your appservers come up again and the
is enforced?
