Android facebook webpage error

[Boomboy222]

When i go onto the spotify app on my android i go to log in on facebook and i put my facebook details in then it takes me to a page after this and does not take me back to the app to show that i have logged in. This webpage is just an error. But i can not log in because it does not connect to the app. I have redownloaded the app and cleared the history on my browser but nothing has hapened. Please help
