HALP! connect() failed (111: Connection refused)?!

ive been trying to dig through this problem for awhile now but cant seem
to view my rails app from outside the LAN. my nginx file prints this..

2008/03/14 17:33:01 [error] 12090#0: *254 connect() failed (111:
Connection refused) while connecting to upstream, client:,
server: my-desktop, URL: "/", upstream: "", host:

ever since my ubuntu box got turned off from a power outage, this
problem came into existence. is nginx having a problem passing the
incoming request to the mongrel? my ports are open, my app is running,
but from outside the lan, no can do.

thanks for any help!
