Can't add the callback to facebook app settings

[Tyvain]

When I try to add the callback's URL in facebook i get this message (also tried with localhost instead of 127.0.0):

is invalid because it is a Facebook url

[Tyvain]

I replace with localhost in 3 place:

• on facebook: 'app domain'
• on facebook: site url ('http://localhost:6789/auth/facebook/callback')
• in config.js: "callback" : "http://localhost:6789/auth/facebook/callback"

Now i am getting this error:

failed to obtain access token (Error: connect EHOSTUNREACH)

@Tyvain Did you create a facebook app for this? And if you did, using that Callback URL?

[Tyvain]

Yes Mickey I did :).

But thing is, I am behind a proxy. Does it matter?

@Tyvain It seems the request was stopped by your firewall npm/npm#6820
