Login fails when not from localhost:3000

[fpservant]

When connecting at localhost:3000, everything is fine. But when using machine's IP address:3000, even from the same machine (and also using 127.0.0.1:3000), login doesn't work.
Seems to be a problem with CORS. Message displayed by safari:

Could not authenticate: Origin http://192.168.1.14:3000 is not allowed by Access-Control-Allow-Origin.

Message in console:

(Using mac OSX latest release)

Don't know whether this is related, but I have several errors displayed in the console when starting:
