Import data app not working

I'm also having issues with this page: http://import.jotform.io/. I try to login but it doesn't redirect me anywhere.

We apologize for inconvenience. I just checked our Import Data app and it working properly at this time.

Please make sure you were log in to your Form Builder already before you load the app.

Here is the screenshot when I test.
