Won't let me log in – MouseHunt: Massive-Passive RPG Review

I was randomly signed out of my account today and I am unable to log back in via the app. When I try to connect with Facebook, after I am temporarily taken to Facebook to log in, I'm simply brought back to the sign in page. When I try to log in with my username and password, I get the message "something went wrong! Please relaunch and try again." I have tried both multiple times after closing the app and reopening, but still cannot log in.
