What Causes the Call of Duty WW2 Error Code 4128?

The error is sometimes caused by faulty Internet connection settings either on your Xbox One or the PlayStation 4. This can only be fixed by either hard-resetting the console or by clearing the MAC address on your Xbox.

If you are a PC gamer, an old graphics card driver may be the culprit for the problem so we recommend you install the latest one from the manufacturer’s website.

Solution 1: Hard Reset Your Console (for PlayStation 4 and Xbox One Users)

Hard resetting your console is probably the best thing you can do when a game starts to display online problems during gameplay. This is evident from the fact that plenty of users managed to solve this exact problem on their consoles simply by following the set of steps we have provided below!

Xbox One:

1. Tap and hold the power button at the front part of the Xbox console until it shuts down completely.
2. Unplug the power plug from the back of the Xbox. Press and hold the power button on the Xbox several times to make sure there is no remaining power and this will actually clean the cache and drain the Xbox from any current.

3. Plug in the power brick back and wait for the light located on the power brick to change its color from white to orange.
4. Turn the Xbox back on as you would do normally and check to see if the Call of Duty WW2 error code 4128 still appears when you start the game.

Alternative for Xbox One:

1. Navigate to your Xbox One settings from the home screenand click on Network >> Advanced Settings.
2. Scroll down to Alternate Mac Address option and choose the Clear option which will appear.

3. You will be prompted with a choice to confirm doing this as your console will be restarted. Respond with Yes and your cache should now be cleared. Open up the game after the console has restarted and check to see if the Call of Duty WW2 error code 4128 still appears.

PlayStation 4:

1. Completely turn off the PlayStation 4 by holding the power button.
2. Once the console is completely shut down, unplug the power cord from the back of the console.
3. Let the console stay unplugged for at least a couple of minutes before you plug the power cord back into the PS4 and turn it on the way you normally do.

Solution 2: Update Your Graphics Driver (PC Users)

If you are playing CoD WW2 on a desktop computer or a laptop, you might consider updating the video card driver in Device Manager as this might help you solve your problem immediately. Video game problems can almost exclusively only be solved by tweaking various driver settings but updating them is the best thing to do!

• Click the Start menu button at the lower left part of your screen, type in Device Manager, and click its entry from the list of results at the top. You can also use the Windows Key + R combination by clicking both of these keys simultaneously in order to bring up the Run dialog box. Type in “devmgmt.msc” in the box and click OK.

Updating the Driver:

1. Expand the Display adapters section in Device Manager, right click on your graphics card driver, and select the Uninstall Device option.

2. Confirm any prompting dialogues which may ask you to confirm your choice and for the process to finish.
3. Look for your graphics card driver on the card manufacturer’s website and follow their instructions which should be right there on the website. Save the installation file on your computer and run it from there. Your computer may restart several times during the process.

Rolling Back the Driver:

1. Right click on the graphics card adapter you want to remove and select Properties. After the Properties window has opened, navigate to the Driver tab and check for the Roll Back Driver button below.

2. If the option is gray, it means that the device wasn’t updated in the last couple of days and it has no backup files remembering the old driver. This also means that the recent driver update is probably not the cause of this problem.
3. If the option is there to click on, click on it and follow the instructions on-screen to go back to the previous build of the driver. Restart the computer and check to see if the problem still occurs when playing Call of Duty WW2.

Note: If you are a Windows 10 user, the latest drivers are often installed together with other Windows updates so make sure you keep your Windows 10 operating system up to date. Windows Update is run automatically on Windows 10 but you can check if there are new updates by following the instructions below.

1. Use the Windows Key + I key combination to open Settings on your Windows PC. Alternatively, you can search for “Settings” by using the search bar located at the taskbar or click the gear icon above the Start menu button.

2. Locate and open the “Update & security” sub-entry in the Settings app.
3. Stay in the Windows Update tab and click on the Check for updates button under the Update status in order to check whether there is a new version of Windows available.

4. If there is one, Windows should start with the download process immediately and the update should be installed the next time you restart.
