How to Fix Diablo IV Code 300010

While Diablo IV players started Tuesday eager to begin the Season of Blood, they instead found themselves facing an enemy very different than demons: Error Code 300010. This pesky error seems to have a preference for console players. In order to get you back to demon hunting as quickly as possible, let’s go over how to deal with the Diablo IV code 300010.

What is code 300010 in Diablo IV?

While the actual cause of error code 300010 isn’t completely clear, it seems to happen when the game interprets your Diablo IV license as invalid. Tuesday’s widespread issue could be from the new update no longer matching the game version console players are running. Since it seems like an issue on the server side, Blizzard is likely looking to address and prevent this issue in the future.

How do I fix code 300010?

There are a few things you can try to fix the issue if you’re getting slowed down by code 300010. First and foremost you should make sure your internet connection is stable and that the servers themselves aren’t having issues. Once you’ve ruled all that out, here are some things you can try:

1. First things first, check for updates and make sure you’re running the most recent version of the game (1.2.0 as of this writing). This is likely most players issue as their game version is out of sync with the server.
2. If that fails- reboot your console. Then, relaunch Diablo IV and see if you still get the error.
3. If that still doesn’t fix the issue, uninstall the game and reinstall it.
4. If all else fails, you may need to reach out to Diablo IV support at Blizzard.

Thankfully, Blizzard is aware of the issue and seems to be working with the community, even delaying the new season to accommodate players unable to login. Hopefully, you were able to fix code 300010 in Diablo IV using this guide, but if you didn’t maybe Blizzard will put that monster in the grave permanently soon.
