How do you fix feral-heart failed to connect to front server?

It probably won't work either if your Wi-Fi isn't connected. Also, it could be that FeralHeart is down. Try downloading the latest patch. If that doesn't work, sorry, but your FeralHeart is not going to work again. c(:

It's probably because you need your computer plugged in if it keeps saying 'Bad Token' or 'Failed to connect to server' . If it doesn't help, I don't know what to do :c
