Call of Duty WW2 is easily one of the most popular battle titles. Users all over the world enjoy the game although they sometimes encounter setbacks with the Call of Duty WW2 application on the Windows platform. In this guide, we intend to examine Error 4128, which indicates a problem affecting the Call of Duty WW2 program.

What is Error Code 4128 in Call of Duty WW2?

Error 4128 is the code that comes up to inform users of the application’s inability to reach or connect to the game servers. Most of the time – when the Call of Duty WW2 app is struggling with server issues – the fault mostly lies in Activision servers being down or overloaded.

If the game is refusing to play on your computer due to Error 4128, you will do well to confirm that the required servers are up and functioning. You can check online forums or communities for Call of Duty WW2 players. There is a reasonable chance that other users are struggling with the same issue.

If you somehow managed to confirm that the Error 4128 issue that manifested itself on your computer has nothing to do with Activision servers being down, then you have to try to resolve the problem from your own end. Anyway, you will learn how to get rid of Error 4128 in Call of Duty WW2 in the next section (below).

How to fix Error Code 4128 on Call of Duty WW2 on Windows 10 computers

Before you begin trying out the fixes to Error 4128, we recommend that you restart your computer and relaunch the Call of Duty application. Sometimes, a simple reboot operation is sufficient to bring about changes to resolve the issues that forced the error in view to come up.

Well, if the recommended restart fails to do enough to make things right, then you can move on to use the procedures below in the order they appear.

1. Run Steam as an administrator:

If Error 4128 has anything to do with the Steam application’s inability to perform certain tasks – especially those that require administrative rights – then the operation proposed here should get things fixed. When you run Steam as an administrator, Windows provides the program and its branches with all the permissions or privileges they need to function well.

Follow these instructions to do the job:

• Verify that the Steam application is currently closed. Confirm that none of its processes or services are active. You can check the Task Manager program to be sure.

If the Steam application is running, you can close it correctly by right-clicking on its icon on the taskbar on your PC screen to see some options and then choosing Exit.

• Now, you must try to reopen the Steam application this way: Right-click on the Steam launcher (or its executable file or shortcut) to see some options and then select Run as administrator.

Your system will bring up a confirmation dialog box or window for the request. You have to click on the Yes button there to proceed.

• Once the Steam application window comes up, you have to go to your Library and then launch Call of Duty WW2. Try to play the game online and confirm that you can now reach the required servers.

2. Verify the integrity of the Call of Duty WW2 game files:

Sometimes, the data read or accessed by applications falls to corruption or becomes damaged. The Call of Duty WW2 app on your computer might be struggling to establish contact with the servers (online) because some of its (local) files have become corrupted or unusable.

Well, the verification procedure for the integrity of game files in Steam is commonly used to resolve corruption issues and damage affecting game data on the platform. You will employ it to check the state of the files used by Call of Duty WW2. During the verification process, bad files will be replaced with good copies of the same data.

Go through these steps:

• First, you have to launch your Steam client. We assumed you have your way of performing this task, so we left out the steps here.

• After the Steam application window comes up, you must click on LIBRARY to see the list of the games you own.

• Locate Call of Duty WW2, right-click on the game to see its context menu and then select Properties.

The Properties window for the selected game will be brought up now.

• Click on the LOCAL FILES tab (to go there). Now, you have to click on the VERIFY INTEGRITY OF GAME FILES… button.

At this point, all you have to do is wait while Steams works to check Call of Duty WW2 files for damage or corruption. The fixes will be applied automatically.

• Assuming the process is complete, you must now launch Call of Duty WW2 on Steam and test things. Instruct the game app to connect to the servers and see how things go this time.

3. Clear Steam cache and cookies

Besides regular data packages (normal files), Steam also uses some sort of cache and cookies to store web stuff for installed games. Well, the items stored in the cache or the data saved as cookies can also fall to corruption or become damaged. Perhaps, issues with those items forced Error 4128 to show up to tell you that things had gone wrong.

By clearing Steam’s cache and cookies, the application is forced to recreate the removed items, which means issues with the old data get eliminated. Here are the instructions on clearing Steam cache and cookies:

• Here too, you have to run Steam as an administrator.

You have to make sure the Steam application is closed. You have to check and confirm that none of its processes or services are active. You can verify everything in the Task Manager program.

To run Steam as an administrator, you must right-click on its launcher (or its executable file or shortcut) to see some options and then select Run as administrator.

• Once the needed Steam application window comes up, you have to click on Steam (situated in the top-left corner of the window) to see its menu list and then select Settings.

The main settings screen for the Steam application will be displayed now.

• Click on Web Browser (one of the items on the list close to the left pane). On the right pane, you must click on the DELETE WEB BROWSER CACHE button.

If Steam brings up a confirmation dialog box or window, you have to click on the OK button there.

• Now, on the same window, you have to click on the DELETE ALL BROWSER COOKIES button.

If you see a confirmation box or window, you have to click on the OK button there.

• Leave the settings screen in Steam and close the application.

• Reopen Steam. Open Call of Duty WW2 and try to play your game online. The issues defined by Error 4128 should have been resolved by now.

4. Update your graphics driver:

Most game problems are a result of computers using malfunctioning or outdated drivers for their components. If you are yet to resolve Error 4128 in Call of Duty WW2, then there is a good chance that one (or more) drivers involved in the operations for the game are faulty or too old. It could be your video or GPU driver, which handles the rendering of images and graphics tasks, or it could be your audio driver, which plays an important role in delivering sound output.

We will first walk you through the automatic driver update process and see what luck you have with it. Follow these instructions to install the latest driver for your GPU device:

• First, you have to open the Device Manager app. You can do this by right-clicking on the Windows icon in the bottom-left corner on your PC’s screen to see the Power User programs and options and then selecting Device Manager.

• Assuming the Device Manager window is now up, you have to double-click on the expansion icon for Display adapters.

Once the selected category expands to show its contents, you should see your GPU driver (NVIDIA or AMD device), which you have to right-click on to see its context menu and then choose the Update driver option.

• On the window or dialog that comes up, you must select the Automatically search for an updated driver version online option.

Windows will now try to contact the necessary servers to see if there is a new driver available for your GPU device. If it finds a newer driver version, it will tell you about it and proceed to download it. You will just have to follow the instructions that come up on the installation wizard window to install the driver.

• Here, assuming you have gotten your computer to install a new driver for your GPU device, you must now proceed to perform the same update tasks for your audio driver. Go through the same steps above, locate your audio driver in the Device Manager app and try to update it through the automatic mechanism.

We recommend that you install as many new drivers as you can for the components involved in the operations or processes for the Call of Duty WW2 application on your computer. This way, you ensure that no driver issue remains unresolved.

If you could not get your computer to install the latest drivers for GPU device – especially if Windows failed to find anything online – then you must go to your graphics card manufacturer’s page and check for drivers there. You will have to select the parameters or options that define your GPU and system configuration.

If you did not find anything useful on your GPU manufacturer’s site, then you have to search for the new driver on your own. Here, you must be mindful of questionable sites and download centers. You must take precautions to avoid downloading malicious programs.

Alternatively, you can spare yourself of all the trouble or complications and get Auslogics Driver Updater to do all the hard work on your behalf. You can instruct the recommended program to scan your computer for driver issues, which means it gets to detect the faulty and outdated drivers. It will then move to fetch the latest manufacturer-recommended versions of those drivers and install them for you.

Most importantly, after you get your computer to install the latest drivers for the devices that matter, you have to restart your computer to round up your work. The necessary changes – some of which ensure the new drivers begin to function – generally become effective after a Windows reboot.

5. Reinstall your Steam client:

There is only so much ordinary operations can do to fix file corruption and data damage. The uninstallation and reinstallation procedures proposed here, however, are made up of processes that bring about serious changes needed to resolve a wide range of issues. Well, if Steam’s files being corrupt or damaged has anything to do with the problems that forced Error 4128 to appear in the Call of Duty WW2 application on your computer, then our recommendation here should be the ultimate fix.

Here, we intend to show you how to reinstall the Steam client without you losing your game data or the progress you made in titles. You just have to go through these instructions carefully:

• First, you have to locate the Steam directory in File Explorer. If you know its location, then you have to use the Windows logo button + letter E keyboard shortcut to launch the File Explorer app and then you can browse through the necessary folders to get to your destination.

Otherwise, you have to right-click on the Steam launcher on your desktop (or its executable file) to see some options and then select Open file location. You will end up in a File Explorer window for the Steam folder automatically.

• You must locate the SteamApps folder, click on it to get it highlighted, and then right-click on it to see the context menu available. Choose Copy.

• Now, you must go to any secure location and paste the folder you just copied. To paste an item, you must do a right-click on any space free of icons or objects in your preferred directory and then choose the Paste option. The Ctrl + V keyboard shortcut should work fine too.

Now, since you have made a backup for Steam games’ data, you can move on to uninstall Steam itself. Continue with the instructions below:

• Press the Windows logo button on your machine’s keyboard to see the Windows Start menu or click on the Windows icon in the bottom-left corner of your device’s screen to achieve the same result.

Input Control into the text field (that typically shows up once you begin to type). After Control Panel (App) appears as the main entry on the search results for the query, you must click on it to launch the needed program.

• Assuming the Control Panel application window is now visible on your screen, you must look to its top-right corner and click on the drop-down menu for View by. From the few options available, you have to select Category.

The items on the main menu screen will be rearranged now automatically.

• Check for Programs and then click on the Uninstall a program link below it. You will be directed to the Uninstall or change a program screen now.

• Check the list of installed applications and locate Steam, which you must right-click on to see some options. Select Uninstall. You might have to click on Uninstall or Yes to confirm things on some prompts or windows.

The Steam Uninstall window will eventually come up. Do as the uninstallation wizard says to get rid of Steam.

• Restart your computer.

• Here, you must move on to install the latest version of Steam available for your computer or system configuration. Fire up your web browser, go to the Steam site and get the Steam installation file. Alternatively, you can search for the application on Google and get the package from other trusted or official sources.

• Click or double-click on the downloaded file to get Windows to run it. You might have to confirm some prompts by clicking Yes or Allow on some windows or dialog boxes.

Do your best to follow the instructions displayed on the Steam installation window. Steam will be installed in no time.

• Here, assuming you have finished installing Steam, you must open a File Explorer window and go to the Steam

You can do this by right-clicking on the Steam launcher on your desktop (or its executable file) to see some options and then selecting Open file location.

• You must now put the steamapps folder you copied earlier in the Steam directory. You can use the Cut and Paste functions to fetch the item from the folder it is currently in and move it to its new location.
