This error can occur due to a weak internet connection. Additionally, the things causing problems can be IPv6 and compatibility issues or IP address problems. When it comes to RPG games, network issues and errors are very common.

Disable Internet Protocol Version 6

IPv6 is probably the reason behind this error. It also causes errors in other games. The IPv6 is mostly not compatible with old games. Disabling it for your default internet connection resolves compatibility issues and can help you fix this error.

2. Select a network from there. In the lower-right corner of the screen, select advanced.
3. Select TCP/IP, click the configure IPv6 pop-up menu, and select off.
4. After applying, then click on the confirmation window.
5. Close system preferences. If you want the changes to take effect, restart your PC.

Hopefully, disabling IPv6 helped you to solve error 1016.

Run Diablo 3 in Compatibility Mode 

Your latest Windows version, say Windows 11, might not be fully compatible with running an old game like Diablo 3. So, to ensure your game runs fine, you’ll need to use compatibility mode to help you run older games on your computer easily.

To run your game in compatibility mode window 7, follow these very simple steps:

1. Locate the game or simply see if you have the game on your desktop.
2. Right-click the game and select properties.
3. Open the compatibility tab on your properties window, click on the box next to the “run this program as compatibility mode ” option choose window 7.
4. Click on “run as administrator”.
5. To save the changes, click on the apply button.

Now, try restarting your game; hopefully, it will help you to fix the error code 1016.

Scan And Repair Your Game Files

If your game files have gone corrupted or missing, scanning and repairing your game can restore them. This is because the error arises due to a violation of the integrity of game files, and doing this process will help solve the issue.

Once the repair is finished, your error will probably be fixed.

Add Diablo 3 To Antivirus Exception List

Antivirus can block your game from accessing the internet. This can result in network connection issues. You can add your game to the antivirus exception list so that it bypasses the antivirus blocking protocols and may potentially fix the error.

After you’re done, close your game, restart, and see if it helped you fix the error.
