Diablo 4Â Season two is finally out, and with it comes a slew of unfortunately expected error codes.
Error code 75 has been an issue in Diablo 4 since its release but emerged once again in October following the release of Season 2, which altered the game significantly, and will continue to occur with every new patch that is released.
Error code 75 can occur for both players on PC and console. Thankfully, it’s easy to fix compared to other issues in the game and does not take too long to complete.
How to fix error code 75 in Diablo 4
Error code 75 in Diablo 4 occurs when you try to run the game using an outdated client, with the message that appears saying that there is a problem authenticating the account.
The most common fix for Diablo 4’s error code 75 merely requires you to restart your console or PC, which should lead to you seeing an update available for Diablo 4. You can also try manually searching for updates on the client beforehand.
Once updated, you will be on the latest version of the client and should not encounter any further issues, though this error may occur again when further patches are introduced to the game, which will require you to follow the same process.

If you’re on PC, you can manually search for updates on Battle.net with the following steps:
- Launch Battle.net
- Select and open Diablo 4
- Navigate your cursor to the Cog button, which can be found next to the Play button on the bottom left
- Click on “Check for Updates” from the drop-down menu
- Install any update that is found
The easiest way to ensure you don’t get error code 75 on PC is by setting Battle.net to automatically keep Diablo 4 updated, which should always keep your game client version in line with the latest updates from Blizzard.
If you don’t know whether there’s been an update and can’t access your Battle.net account on PC, you could check the official Blizzard channels, such as the latest Diablo 4 patch notes and the Blizzard Forums.
Any change in the patch notes will indicate there’s a new version of the game, which means you could be at risk of encountering error code 75 when you’re back.
