Diablo® III Connection Troubleshooting

Keywords: lag, latency

If you are having problems connecting to Diablo® III, or find yourself disconnecting frequently, please follow the steps below to troubleshoot the disconnection issue.

Note: For players in North America, Australia, and New Zealand, your play server is based on the regional location of your party leader. For example, if you are in North America and you join a party led by a player in Australia, your connection will be routed to the Australian server.

Windows

  1. Before doing more advanced troubleshooting, check that the Diablo III server is not simply down for necessary maintenance. Check the Breaking News section of the Diablo III login screen or the Diablo III Server Status page.
  2. Your router may become flooded with data and drop your connection to your ISP. Reset your network devices to address this.
  3. Configure your network to ensure that your connection is not being blocked by a firewall or router.
  4. Our games require an up-to-date operating system in order to run properly. Run Windows Update to be sure you're using the most recent version.
  5. Old firmware on your modem and router along with old drivers on your network card can cause issues when your network needs to deal with complex game connections. The manufacturer's website for your hardware should have firmware and driver downloads available, as well as instructions on how to apply firmware updates.
  6. Security software may interfere with the Update Agent. Disable or temporarily uninstall any security programs.
  7. Programs running in the background can interfere with the game. Close any running background applications.
