6 Fixes: Diablo 3 Error 1016

Are you getting error 1016 in Diablo? There are several reasons for this error. But don’t worry. This is a guide that will tell you all about it.

Diablo 3 has become a popular game since its release in May 2012. This is one of the most addictive hack-and-slash games out there. But more than ten years have passed since its release. So, it’s natural to run into a couple of problems.

Let’s start with the first question that pops into everyone’s head:

What is error code 1016 in Diablo 3?

Error code 1016 is a connection problem. This is due to network issues. So, when you encounter error code 1016, this is one of the common problems.

There can be many reasons for connection problems. Sometimes this was due to the inability to connect to the server. The Diablo server may not be available for you to play the game. Let’s check all the causes of this error:

Causes of Diablo 3 Error Code 1016

There can be many reasons for error 1016 in Diablo 3. Here is a list of all probabilities:

1. Using IPv6

Diablo 3 was released in May 2012. Internet Protocol version 6 began to gain popularity in June 2012. During these years, until 2015, IPV6 was not used as much. As for Diablo 3, it does not use IPv6.

This can lead to problems as the game is not ready for an extra layer of security. As a result, it may not even understand the IP address. This leads to problems.

2. Error with IP address

Another related issue has to do with the IP address itself. This can happen even if you are not using or have disabled IPv6. The internet connection IP may not work for Diablo 3. So you may need to change to see what will work for it.

This is the same as the previous error and causes similar connection issues.

3. Problem connecting to the server

Network devices and connectivity aren’t the only issue. A server issue could also be the cause. Diablo 3 is an old game and the server may lose connection with the game. There may be very few options available, fewer servers and the like.

Diablo 3 is a popular game, but not the same as before. So server downtime is possible.

4. Antivirus blocks the game

The problem may be interference from a third-party application. First of all, it may be a third-party antivirus. If you use any premium antivirus, you may need to make Diablo 3 an exception.

Antivirus may have blocked Diablo 3 as a foreign object. This is a fairly common problem, especially in recent versions of Windows. So, be sure to check it out. It could also be your Windows Defender, so check that out.

5. Firewall is blocking the connection

Firewall is another security feature related to internet connection. It can allow the connection from the application or deny it. The chance that a firewall will block Diablo 3 is the same as an antivirus.

It can be considered as a foreign object. So it’s a good idea to check your firewall settings and see if Diablo 3 can be allowed.

6. Damaged files or installation

Not all problems are related to Internet protocols (Internet Protocol) or IP direction (IP address). Sometimes it has to do with installation. The files may have been corrupted, resulting in a conexión (connection) problem.

So, if you are facing this issue (problem), it is time to reinstall Diablo 3. Often, reinstalling can help you fix all problems. So, it’s worth a try. You can also verify the integrity of the game file.

Checklist before starting

• Check the status and speed of your internet connection. Make sure it provides the right speed for your gaming experience.

• Reboot the router if necessary. Reconnect network services. You can even reboot network devices.

• Check for driver updates and operating system updates (Windows or macOS).

How to fix Diablo 3 error 1016?

1. Try a VPN connection
2. Use compatibility mode
3. Reset IP address and clear DNS
4. Disable IPV6 protocol for the game
5. Add Diablo to your antivirus exclusion list
6. Disable antivirus software

1. Try a VPN connection

Server issues are fairly common in older games like Diablo 3. If you’re having problems connecting to a server, it’s worth trying a VPN.

You can find many free and premium VPNs. As a general rule, you should always use a premium VPN. Most premium VPNs come with free trials and value-added subscriptions.

In any case, if you’re not using a VPN, get a trial first and see if it’s worth investing in. If not, you can always get more VPNs for a trial.

Here are the steps to follow:

• Download and install VPN
• Then find out which region has an active Diablo 3 server.

• Connect to the VPN server in that region.
• Then launch the Diablo 3 game and connect to this server.
• See if this solves the problem.

2. Use compatibility mode

Windows 10 and 11 are the latest additions and Diablo 3 may not be set up for them. Even though Windows 10 comes with backwards compatibility, not all games work.

So, this step is worth checking out. After all, Windows 10 and 11 have the brilliant Compatibility Mode feature.

Compatibility mode allows you to use applications, games and software for the previous OS. These are tools not available for the latest version of Windows OS. So worth a try:

• First, find the Diablo 3 shortcut on your desktop. If you don’t have it on your desktop, go to the directory where you keep it.
• Next, right-click on it; if it’s a shortcut, you’ll see “Open File Location”. Select it.

• This should take you to Diablo3.exe or something similar.
• Right-click the file and select Properties. This will open a new window. You will be on the General tab.
• Change the tab to Compatibility tab.
• There you will find many options. Look for the one that says “Run this program in compatibility mode.”Install it and select Windows 7 from the dropdown menu.

• Click Apply and then OK.
• Run and see if the Diablo 3 error fixes it. If not, it’s a good idea to visit the Compatibility tab again.
• This time, click “Run this program as an administrator”.
• Apply and save the changes again and see if that solves the problem.

3. Reset IP address and reset DNS

As you can guess from the issues, the Diablo 3 error is related to the network connection. More specifically, the IP address. Thus, trying to update or reset your IP address is natural.

This step may help resolve the issue faster. All you have to do is:

• Launch the Run utility. You can press the Windows icon key and the R key (Windows key + R key) at the same time. This will launch the Run utility.
• Then type “cmd”in the Run dialog box and press CTRL + SHIFT + ENTER.

• This will launch a command prompt with administrator privileges. You will need it for commands.
• Now enter the following commands and remember that you must press Enter after each command without a space. After pressing Enter, type the following command and follow it:

Ipconfig / flushdns
Ipconfig / release
Ipconfig / release6
Ipconfig / renew

• After these commands, you can print.”Exit‘ and press enter. This will close the command prompt.

4. Disable the IPV6 protocol for the game.

Many older games are not compatible with IPv6. Your Diablo 3 game is also one of those games.

So it’s better to disable IPv6 if you plan to play Diablo 3 and other old games.

• First, you will need to open the Control Panel. There are different methods for this. Your best bet is to search for Control Panel in the search bar at the bottom left corner (Start Menu).
• In the Control Panel window, find and select Network and Internet from the list.
• You will find “Network and Sharing Center”listed. Select and open it.

• You will see the currently active connection. In the left section of options, you will see “Change adapter settings”. Click here. This will take you to the network adapter settings.
• A list of all connections will open. Right click the one you use for gaming. Then go to Properties.
• Under the Network tab in the new window, you will see various settings. Check the “Connection uses a list of the following items.
• You will see Internet Protocol version 6 (TCP/IPv6) listed. Clear the checkbox. If it has already been removed, so be it.
• Be sure to click OK to save your changes.

See if this solves the problem. The connection should work fine. Do not uncheck TCP/IPV4 by mistake. Continue. Make sure nothing has changed.

5. Add Diablo to your antivirus exclusion list

Your antivirus software can create several problems. This may block the game from starting or establishing a connection.

Each antivirus will have different instructions for adding a game to the exclusion list. Here we list the quick steps for some popular antivirus programs:

• For Windows Defender: Start Menu > Settings > Update & Security > Windows Security > Virus & Threat Protection. From there, go to Manage Settings > Exclusions > Add or Remove > Add.

• For AVG Antivirus: Home Interface > Settings > Components > Web Protection > Exceptions.
• For Kaspersky Internet Security: Home interface > Settings > Advanced > Threats and exclusions > Exclusions > Specify trusted programs > Add.
• For Avast Antivirus: Home > Settings > General > Exclusions.

After that, go to the folder directory and add Diablo3.exe to the list. You can also add the entire folder to prevent problems in the future.

6. Disable your antivirus software.

If adding to the exclusion list doesn’t work, or if your antivirus doesn’t have it, you can disable it. We do not recommend doing this if you are using a premium security tool.

But you can disable your antivirus for the duration of the game. After that, you can reactivate it and scan the system for potential danger.

Each antivirus will have its own method of disabling or closing. So you might need to check it out.
