Can't access the game

Every match I get a resource error or a network error message even though my internet seems to be perfectly fine. I tried to restart my phone and the game but with no hope. Tried reinstalling the game and now keep getting download error and network error messages and can't even enter my account or the game. On time I finally entered but all I got was that grey screen I attached here. I really wanna finish my daily quests before they end. Thanks
