On your system "myhost.local" resolves to three different addresses (127.0.0.1, ::1, and fe80::1). Node prefers ipv4 over ipv6 so it'll try to connect to 127.0.0.1. Nothing is listening on 127.0.0.1:8080 so the connect() syscall fails with ECONNREFUSED. Node doesn't retry with any of the other resolved IPs - it just reports the error to you. A simple solution would be to replace 'localhost' by the intended destination ip address, '::1'. Whether this behavior is right is somewhat open for debate, but this is what causes it. - Bert -- -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
