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.
