What is “Status Code: CO2 504”?

Simply put: Status Code CO2 504 is an error informing you that the game’s network connection is unstable. While the error tells you to check the connection on your end, this is most likely a server issue. Many users were having this issue the moment that the game launched, suggesting that the servers were getting overloaded with too many players connecting at once. Shortly afterward, the servers were taken down for a maintenance check to resolve the connection issues.

How to fix the error

At the moment, there is no quick solution to fixing this error. As mentioned above, the issue is server-sided, so the only solution right now is to simply wait and come back to the game at a later time. When the number of players coming to the game slows, or once the developers have finished performing maintenance, the error should stop appearing for you. Also: Make sure that you’re connecting with a stable internet connection and are attempting to play in areas that have decent connection speed or wi-fi strengths before attempting to log in.  At the time of this article, an official statement on the FFVII First Solider website has mentioned a completed maintenance check on the servers, so any serverside connection issues should be resolved by now. If the issue persists, just be sure to log off and try again while checking your own connections.
