NBA 2K21 has suffered its share of issues since launch day. Players have had problems with downloading rosters and classes, and other error codes such as 4B538E50. The latest issue to emerge is error code 727E66AC, which stops players from accessing various parts of the game, such as MyCareer or Park modes.
If you’ve run into this problem, you will have received a pop-up message that reads, “There is a problem with your connection to our online services. Please visit ‘www.NBA2K.com/status’ for up to date information”. You will, then, want a fix to ensure that you can carry on playing NBA 2K21.
Unfortunately, there isn’t an official solution. The 2K Support Twitter account has not mentioned this error since it emerged, and there isn’t a specific page for it on the official 2K support website either.
