The game was back up for a period of time yesterday then people started having some issues again, it seems to be working fine for me and many others, try restarting your game or checking internet connection maybe? Unless the server is still down for people in some places.
i shut down the game, and rebooted it and even went to uninstalling and re-installing the game...
Do you have the Login page open? And if so, refresh it every so often. At times, it will log you out randomly and not show any signs of it actually logging out. Refreshing will cause the little 'password' and 'username' menu to pop up.It's beginning to do something similar to me as well, but it could just be the internet I have.

Keep the login page window open and not minimized. Try different browsers or signing in on mobile. If all else fails try testing your connection on another game. It might just be the server not having a good connection in your area right now.
