Trouble with app and connection

I have had my Tidbyt working for quite some time. Now it is not able to hold a connection. I have tried resetting it and uninstalled the phone app on Android. I can not even get the app functioning on my Tidbyt. I can get to the log in screen. But a message pops up saying that I can not get connected. Please try again later. I am not sure of what to do about this.
