getting 502 errors when trying to talk to mongo

Hi all,

Is there any specific versions of node/mongo/nginx that will get this to work?
acmeair builds fine, and comes up fine.  But everytime i tried to load the db, i get this error:
Error: Unable to load http://test.xyz.com/customer/acmeair-cs/rest/api/customer/config/countCustomers status:502

Can someone share the versions of mongo/node/nginx where they got this to work?

thanks a mil
