How to Fix Diablo 4’s Error Code 75

Perhaps the most common error code currently plaguing the game is code 75, which provides the following message: “There was a problem authenticating your account.” It sounds worse than it is, though. Don’t worry; once the error code disappears, you still own a legit copy of Diablo 4 and are fully capable of playing the game.

To fix error code 75 in Diablo 4, close out of the game and check for a Diablo 4 update. Code 75 generally appears because your game is out of date, and you’re attempting to connect to the live servers. You may need to force your system to update. On Steam, you can right-click the game and navigate through Properties and Installed Files to “verify game files.” On Battle.net, a gear icon allows you to check for an update. On consoles, restart your system. A restart should force the game to update once you’re back on the home screen.
