itpp2012,
i believe my issue is not separate from the ipv6 issue.
In any case the errorlog for the ipv6 problem is the same:
2014/01/30 10:32:32 [error] 6760#3604: *1 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /api/xxxxx HTTP/1.1", upstream: "http://[::1]:3000/api/xxxxx", host: "localhost"
the url http://[::1]:3000/api/xxxxx is the correct URL if we call localhost throught the ipv6 interface.
