Driver Update

  • You can start by attempting to update your network drivers. If outdated drivers bring on the problem, this could fix it. You may update your drivers using Windows Update, a driver updater that is free to download, or by going to the manufacturer’s website for your network driver.
  • Try opening the ports that Diablo 3 utilizes if upgrading your drivers does not fix the problem. If a firewall prevents the game from connecting, this may fix the problem. The ports used by Diablo 3 are:

                                           TCP: 80, 443, 1119, 3724

                                         UDP: 4000, 6112, 6699, 7000-10000

Turn Off Firewall 

If you’re experiencing “Game Connection Lost” errors in Diablo 3, there are a few things you can try to resolve the issue.

First, try turning off your firewall or allowing the game to pass across it. Your firewall and antivirus software may be a contributing factor. Try temporarily deactivating your third-party antivirus program if you have one. Try turning off your Windows Firewall or allowing Diablo 3 to pass over it, though, if you are using one. The methods to let the game via the Windows Firewall are as follows:

  1. Go to Start > Control Panel.
  2. Select Windows Firewall.
  3. Select Allow a program or feature through Windows Firewall from the left side of the window.
  4. Click the Change settings button.
  5. If Diablo 3 is not listed, click the Allow another program button.
  6. Click Browse and select Diablo 3 from the list.
  7. Select Add, then select OK.
  8. To dismiss the Windows Firewall window, click OK.

Try reverting your network equipment to factory settings if you still get “Game Connection Lost” messages. Re-connect the modem and watch for the lights to steady after 30 seconds. 

Check Your Clean Boot

An ongoing connection to the game servers is necessary for the online game Diablo 3. You are unable to play the game if your connection is lost. There are some potential causes for this, but the most frequent is a problem with your internet connection.

Try rebooting your router first. If it doesn’t work, try using Clean Boot for debugging. This will turn off all extraneous services and programs that could be the problem. Once you’ve identified the program causing the issue, you can uninstall it and hopefully resolve the connection lost issue.


If everything else fails, you could try resetting the game’s settings. All settings will be restored to their default positions as a result. Therefore, if there was a problem, it should be resolved right away. Reinstalling the game is the last step if all other attempts have failed. So, before doing this, be careful to back up your stored files.
