Android Stuck on load screen.

I was logged left my phone unlocked with the app still running. Left it for about 10 min. When I came back my screen was where I left it focused in the realm on 2 resources I was collecting then I moved the screen and the app started loading. Waited maybe a min and when nothing happened I just closed the app and figured I'd just reload the app. When the app opened back up it showed the "Loading... Please wait"message. Then the "Logging in...." Message followed by the message "Service unavailable... Retrying".Now it says "Remote call Failed: 502: Bad gateway... Retrying" Just wondering if is something wrong with my account or app or if this is just maintenance.

 

Nevermind it's working now received a message about high volumes of players
