I keep getting 520 message And game won't load!!!

If your game is not loading please follow the instructions from the following link.

520 can be caused by many issues, these can include connection reset, or invalid response or unexpected response from a server. investigate the issue carefully. 

Refreshing, and trying to access the game in a few minutes should solve your problem.
