  2. Unplug the router and modem from the power source.

  3. Wait for about 60 seconds before plugging the modem back.

  4. Wait for the lights to turn green then plug in the router.

  5. Start Diablo 3 and see if that fixes the problem.

3. Change your Diablo 3 Region

Diablo 3 allows you to pick the in-game region. But some regions are more popular than others and these regions would get overcrowded with players pretty quickly. Accessing overloaded regions is difficult and could trigger error code 3006. You just need to switch to another region.

  1. Close Diablo 3 and launch the game client.
  2. Click Options and select Account.
  3. Scroll down to the Server Region and click the dropdown menu to expand it.
  4. Select a different region and click OK to save your settings.
  5. Launch Diablo 3 and log in to continue your gaming experience.

Much like your router, the DNS cache gets corrupted or outdated. This can create connectivity issues and trigger errors when playing online games.

  1. Shut down all apps that might be using the internet including Diablo 3.
  2. Right-click the Start menu and select Windows PowerShell (Admin).

  4. Wait for the process to finish then close Windows PowerShell and restart your computer.
  5. Relaunch Diablo 3 and make sure you can log in without any issues.

5. Troubleshoot your Network

When none of the above solutions seem to work, the problem might be in your network configurations. The best way to fix that problem is to launch the network troubleshooter and let it find out what’s wrong with your network and offer you options to fix it. 

  1. Open Settings from the Start menu and select Update & Security.
  2. In the left panel select Troubleshoot.
  3. Scroll down to Additional Troubleshooters and click it. Launch additional troubleshooters
  4. In the new screen, click Internet Connections to expand it and hit Run the troubleshooter. Launch internet troubleshooter
