Diablo 4 Season 2, after a short delay, has finally gone live. However, the never-ending string of error codes has reared its ugly head. These error codes are associated with specific issues for easier identification and troubleshooting. A major chunk of these codes appears after an update has gone live or at the launch of a new season.
The Diablo 4 300010 error code is usually seen during a brand-new season or an update. That said, here's why the error occurs and its possible fixes.
How to fix the Diablo 4 error code 300010
The Diablo 4 300010 error code occurs if the installed version of the game isn't up to date with the latest patch. This is why it's spotted whenever a new season has gone live or a patch is available.
The only way to fix this issue is by downloading the new update before launching the game. Under normal circumstances, the update is downloaded and applied automatically. However, if you've changed the settings in the Battle.net app, you must manually download the new patch before attempting to run the game.
That said, if you haven't changed the settings and keep getting this error, you can restart the Battle.net app. This should automatically lead to downloading the new Diablo 4 update. If the process is not triggered, here's what you need to do:
- Launch the Battle.net app.
- Navigate to the Diablo IV page.
- Besides the play button, there should be a small button with a cog wheel on it.
- Click on this wheel and select the "Check for Updates" option.
- The app will now automatically check for updates and download the new files (if any).
- In case there is no new update available, then a small message saying "files up to date" should appear below the big blue play button.
To prevent this error, ensure that automatic updates are turned on. If downloading the new update does not solve the issue, there's a high chance that your game files are corrupted. In that case, the only solution is to perform a clean install from scratch.
