Diablo 4’s error code 300022 occurs when you have trouble connecting to the game’s servers. In a lot of cases, the issue is server-side so you might not be able to do anything about it until Blizzard addresses the login issues. But if you are facing the issue due to connectivity problems, there are some fixes that you can try. Here is a quick guide on how to resolve Diablo 4’s error code 300022.

How to fix Diablo 4 error code 300022

Before trying any fixes, make sure you head to the BlizzardCS Twitter account to check if there are any ongoing server issues. It is possible that the Diablo 4 servers are facing issues that can lead to the 300022 error code in Diablo 4. If there are ongoing issues, you’ll need to wait it out until a fix is deployed.

If the servers are online and you are still unable to enter the game, here is a fix that could resolve the issue. 

  1. Press the Windows Key

  2. Type “Command Prompt” and hover on the first app result 

  3. Click on Run As Administrator

  4. If asked whether to allow Command Prompt to make changes to your computer, select Yes.

  5. You should now get a new window with a black screen.

  6. Type "ipconfig /flushdns" and press Enter.

  7. Type "ipconfig /registerdns" and press Enter.

  8. Type "ipconfig /release" and press Enter.

  9. Type "ipconfig /renew" and press Enter.

Ideally, you should not face the 300022  error code after flushing your DNS. However, it is possible that you are facing DNS issues because of your internet service provider (ISP), and you can consider seeking technical assistance from your service provider. Using a virtual private network (VPN) can also temporarily alleviate the issue.
