Cordova (ios) doesn't work for login; connecting to server?

I try to build my first cordova mobile app with meteor. But I do not understand the thing completly.

I’ve added the ios package and I build the app like this:

meteor build ../build --server localhost:3000

I can open and run the Xcode project successfully.

At the beginning the user can login (as on the webpage). Therefore I’m using

accounts-base
accounts-password
accounts-ui
useraccounts:bootstrap
alanning:roles

But after submitting the user data everything is stucked on the loginProcess.

template(name="main")
	if authInProcess
		+loginProcess

	else
		h1 Content

So just the loginProcess template is beeing displayed. On the webpage this element is just shown for a second, then the content is beeing shown.

I also tried to build the app with this (SSL):

meteor build ../build --server domain.com:443

But still not working. Maybe the app can’t connect to the server?? How can I check that? But if this would be the case, why do I see the start page with the login form?
