With the arrival of any new update in Diablo 4, we get new and recurring errors that stop players from logging into the game.

Most of these errors are categorized under unique error codes that help identify and fix the main issue. One that players have been facing quite a lot is error code 75 - so here's why it occurs and how you can fix it. 

What is Diablo 4 error code 75?

Occasionally, when launching Diablo 4, you'll be met with error code 75 alongside the message, 'There was a problem while authenticating your profile'. This happens when the current game client is not up to date.

Since Diablo 4 is a live-service game, you cannot play it offline or with an old client. 

Since the developers often release new patches without prior notice - aside from major updates - some players won't even be aware of a pending update. When they try to play Diablo 4, they'll be met with error code 75.

To fix Diablo 4 error code 75, you'll need to close and update the game to the latest version. Once that is done, you can start the game again, and the error should be gone.

To update the game on PlayStation and Xbox platforms, simply restart the game while connected to the internet or press the 'Option' button and 'Check for updates' to start any pending updates manually. 

On PC, if you have the game installed via Steam, open the app, go to the 'Library,' select Diablo 4 and click on the 'Update' button, assuming the update didn't start automatically. On the other hand, if you are playing the game via Battle.net, open the launcher, select the game and update it via the Options menu. 

Updating the game is the most definite fix for error code 75, regardless of the platform you're using. If you still can't log into the game, I'd recommend checking the game server status and internet connection or contacting Blizzard Customer Support.
