A large number of login attempts can lead to server errors in online games. In Diablo IV, Error Code 30008 can crop up when you try to log into the game. Blizzard’s latest action RPG title is an “always online” game that highly depends on your ability to connect to the internet. But conversely, that also depends on the game’s servers being able to grant you access in a timely manner. Error 30008 is connected to this issue, but fortunately, there are a few ways to try and fix it. In this article, we will explain how to fix error code 30008 and what it is in Diablo 4.

How To Fix Diablo 4 Error Code 30008?

While many errors can be connected to internet issues, like the similar Error Code 401003, Error Code 30008 can be a bit more deceptive. There are several different possible solutions depending on the culprit, and we will help you check for all of them. Follow these steps to resolve Error Code 30008 in Diablo 4:

  • Press Try Again – First, the error prompt itself will offer you the option to Try Again. Press the button to see if it was just a temporary snag. If that doesn’t work, follow the list of steps below to troubleshoot the issue.
  • Check the Diablo 4 Server Status – If the servers are down, then there’s not much you can do about it except to wait it out. You can use a service like DownDetector to perform a quick check or follow the game’s social media like Twitter for any service issue announcements.
  • Check Your Internet Connection – Your router or even your ISP may be experiencing connectivity issues. Try restarting your modem and router, and if the problem persists, contact your ISP to check if everything is working on their end.
  • Try Flushing DNS (PC Players) – You may have bad cache files from previous gaming sessions which prevent you from reconnecting to Diablo 4 servers. To flush DNS on Windows, look for Command Prompt by typing cmd in the search bar. Right-click on it and select Run as Administrator. Then type out (or copy and paste): ipconfig /flushdns and press Enter. After it’s done, close Command Prompt and make sure to restart the Battle.Net client and Diablo 4.
  • Firewall and Anti-Virus Software – These types of software can block Diablo 4 from connecting to Blizzard’s servers. You can try temporarily disabling them, but a better solution is to add Diablo 4 to the exception list in the app’s settings.
  • Verify Your Diablo 4 Game Files – Sometimes installed game files can become corrupted or end up missing, so it’s a good idea to check if that’s the issue in your case. Click on the cog icon next to the Play button in the Battle.Net client and select the Scan and Repair option.
  • Contact Blizzard Support for Diablo 4 – If all of the above solutions fail, you should contact the Blizzard Support service for Diablo 4. They should be able to guide you through more specific troubleshooting or inform you if the problem is largely on the server end.

What Is Error Code 30008?

Error Code 30008 is a catch-all code for an issue with DNS communication between your device and Diablo 4 servers. That makes troubleshooting the issue somewhat troublesome because the cause could be on either end. For example, you could get Error Code 30008 for a bad DNS cache on your device, but it could also happen because the servers are down or there is login throttling on Diablo 4 servers due to too many login requests. Therefore, it’s best to attempt all of the proposed solutions above to try to narrow down the culprit.
