Xfi app does not work - XFinity

We just had our wifi fixed 3 days ago because the wifi was not working. Now, the wifi is working but the App itself does not work. I have uninstalled, put the app back, restarted my iphone, still shows the same message “your gateway may be offline”. But our wifi is working, its just the App that wont let me in.
