I am creating a Meteor app with Facebook login. It works fine on localhost, but when I deploy it to meteor.com, it doesn't work. Facebook does not even let me register the app. When I enter the Site URL, I get the error message: "This URL contains an invalid domain", though the domain,

   http://nr_siteaces.meteor.com

is a perfectly valid URL. I have tried adding meteor.com as app domain, but that does not improve things. I have also read the following articles, but they do not adress the issue:

Meteor login with facebook

Meteor app - facebook login - popup doesn't close

Facebook Authentication with Facebook app error

Facebook App: localhost no longer works as app domain

I had the same issue and the only solution for me was to remove the underscore (_) from the URL. I couldn't find any documentation which explains why the underscore invalidates the URL but it seems to do so in Facebook's view.

Edit: This answer seems to shed some light on the "underscore in a URL" issue: https://stackoverflow.com/a/2183140/2088912 so I guess Facebook is just following the rules.
