For the past week i've been getting dropped from the game and then after being dropped I am unable to get back in.  I am getting the error screen as shown below.  I've tried closing the game, clearing the cache, and completely uninstalling and reinstalling.   If I reboot my computer occasionally I can get back in.  I've run a few tests on my internet connection and it seems to be fine.  I don't ever seem to lose connection to the internet when I lose connection to the game.  Any suggestions for fixing this would be greatly appreciated.  The error screen i'm getting is below.
