Diablo 4 error 30008 troubleshooting

It appears as though error code 30008 is a DNS error between client and server, perhaps better understood as a confusion between the player and Blizzard. In order to attempt to solve this, you’re going to want to conduct multiple troubleshooting steps, in order, so we’re applying the least amount of force necessary to solve this. Further, note that this can be an improperly attributed error based on server congestion and server-related errors on Blizzard’s side, which means you’ll simply need to wait for a fix.

Complete these steps, in order, to fix error code 30008:

  • Turn the game off, exit the Blizzard launcher, and attempt to restart the title.
    • If the issue persists:
  • Exit the game, and select ‘Scan and Repair‘ within the Blizzard launcher, and attempt to start the title.
    • Only if you continue to receive error 30008:
  • Enter the command prompt, and enter ‘ipconfig /flushdns’ as an administrator.
