Some NBA 2K21 players are having trouble playing, they cannot connect to the game, and error code 72766ac is displayed – what error is this?
NBA 2K21 seems to have the same problems as NBA 2K20, in the first few weeks after the release more problems occur that annoy players.
The above error 72766ac seems to be a global server failure, this has now been officially confirmed.
NBA 2K21 error 72766ac Fix
At the moment there only seems to be a solution for the NBA 2K21 Mamba Forever Edition, 2K has already released a hotfix here.
If you get this error code, there is nothing you can do. The only thing you can do is close the game and try again. Some players have reported getting into the game after trying several times.
We assume that an NBA 2K21 hotfix update will be released shortly, which will be update 1.02 on the PS4.
