Before we begin with the methods to fix the issue, it is important to address the preliminary steps that you should take to ensure that no basic issue is causing the error. Basic issues such as network connectivity, internet errors, etc.

Here are the things you should try to fix the connection loss error – 

1. Restart the Battle.net client on the PC to ensure it is not just a temporary glitch.
2. Disconnect the current internet connection and reconnect it to reset your connection.
3. Try launching another game to check if it is a game-specific issue.

Fix 1 – Add Game to Firewall Exceptions

In case the server keeps disconnecting, there are chances that the PC’s firewall is not allowing the application to access the internet properly. The best solution is to allow the application through Windows Firewall. Here are the steps that may help you do the same – 

Step 1 – Press Win+R to open the Run search. Use the command Firewall.cpl and hit enter.

Step 2 – After opening the Firewall menu, check the left pane to find Allow an app or feature through the Windows Defender Firewall option. Click on it to open more options. Step 3 – To edit the list of allowed features and programs, simply click the Change Settings button. You must be logged in as an administrator; otherwise, you may not be able to use the feature.

Step 4 – After clicking on Change settings, the list becomes available to edit. You can now scroll to find the Battle.net or the Call of Duty process in the list. If you cannot find the error-causing app in the list, click the Allow another app… button, which is now available to open.

Step 5 – The allow another app button will open the select app window. From there, you can click on browse, which will open the explorer for you to select the .exe file for the process.

Simply browse through folders and select the app you want to allow. In this case, it is either the game that cannot connect to the Blizzard game server or the Battle.net client.

Step 6 – Once you have selected the file, click the Add button in the Add an app window, and it will appear in the list.

After successfully adding the app to the list, exit the settings and restart your PC. Launch the game and check if it is working fine now. If this was the issue, it should not show the connection to the game server lost error message. However, it still appears, do not worry, as we have other fixes as well. 

Fix 2 – Reset Network Using Command Prompt

There is a chance that the issue related to the server connection is caused by the network data that your PC has stored after using the connection several times. Giving it a quick reset will help you out. 

Step 1 – Go to the start menu and search for CMD. Run the Command Prompt as Administrator to open it.

Step 2 – Use the following command one after the other to get rid of the issue –

(Press enter after each command)

netsh winsock reset

netsh int ip reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

Step 3 – Try launching the game again, and you should be good!

This network reset makes your connection completely fresh, so if that was causing the issue, it will be resolved instantly!

Fix 3 – Update the Drivers on Your Device

If the network connection shows signs of error, but the bandwidth and the connection data are OK, it may be due to your PC’s ability to connect and use that connection. The drivers on your PC are responsible for a lot of self-explanatory processes. For instance, supporting the network to connect is the job of the Network Adapter Driver, ensuring visual clarity is the job of your GPU driver, and so on. 

The thing to understand here is that these drivers require regular updates. Without these updates, these drivers are no good and cause issues. It is important to know how to update the drivers on Windows. But if you do not know it yet, do not worry; we have just the correct application. 

If you are struggling with these errors due to outdated drivers, try Advanced Driver Updater. It is the easiest way to update the drivers. It only takes a few minutes to finish the three-step process – 

Step 1 – Download and install the application on your PC.

Step 2 – Run a scan using the application to identify the outdated drivers on your PC.

Step 3 – Once listed, click Update All, and your job is done!

Now, the tool will find, fetch, and install suitable updates without you having to do anything. The PC restarts automatically after the updates are installed, and you are good to go. After the C restarts, try launching the game that had a connection to the Blizzard game server lost issue, and you will see that it is now resolved. 

Other than these fixes, also ensure you disconnect the VPN if you use one. Try updating the game, as compatibility issues sometimes also take over. Update your PC for the latest OS, as it does contribute to supporting the PC. 

All of that should help you out. Feel free to ask for assistance in the comments section if you get stuck at any point. That will be all for this post; thanks for reading. Good luck!
