Backstopjs [url changed to "about:blank"]

i'm having trouble to use scripts, i see this problem in another issues but i can't resolve it.

my application has a login page and when some one make a login it takes you to the first page localhost:3000/#/potenctial, and it's appears to occurs, but it take me back to the login page, and then to a blank page.

localhost:3000 is the login page and localhost:3000/#/potential is the first page after login success

• Detail, it happens in any page who i try to login. like facebook

i was thinking it could be something with the installation, but i installed everything in other Ubuntu and same happens.

that is the terminal output

• node v7.10.0
• backstopjs@2.6.11

backstopjs is installed locally.

Thank you, and just to be clear i'm new on node, so it maybe not even be a bug.
