Xfi app not working - XFinity

My Xfi app stopped working about 3-4 days ago, it says my Gateway is offline. I know it's not, as the wifi is up and running, and I can access Xfi through the Xfinity online website, as well as get in the modem via its ip address, so it has to be a problem with the app itself. I've done all the normal stuff like flushing cache, deleting, shutting my phone down and reinstalling several times, and nothing works.

Any ideas what's going on Xfinity?
