(Solved) Error BLZBNTBGS000003F8 in Call of Duty: Black Ops Cold War

Call of Duty: Black Ops Cold War turned out to be a rather problematic game, during its existence dozens of bugs were found. One of the last is BLZBNTBGS000003F8, it appears during the game. Although CoD is launched initially, the game becomes completely unplayable. We have thoroughly studied this failure and are ready to offer real solutions that have already worked for many players.

Solution 1: bring the game to firewall exceptions

Windows Firewall is needed to protect programs and files from unauthorized operation. However, under certain circumstances, it can block even the software that does not harm the system. In a similar situation, access to the network is blocked and Call of Duty: Black Ops Cold War simply crashes with an error.

How to fix error BLZBNTBGS000003F8:

  1. Open Windows Firewall (you can find it using the search).
  2. Click on the option in the vertical menu “Allow interaction with the application …”.
  3. We look for this game in the list and set flags in both columns.
  4. Save changes and close the window.

If there is no CoD in this list, then the problem is definitely that the game does not have access to the Internet. To fix this, you need:

  1. Launch Blizzard launcher and select this game.
  2. Click on the Blizzard image and go to Settings.
  3. On the “Downloads” tab, look for the folder where the game is installed.
  4. We go along this path and look for the BlackOpsColdWar.exe file.
  5. Copy the path to it.
  6. We return to the firewall menu and click on the “Allow another application” button.
  7. Insert the path and click “Add”.

Method 2: clear the DNS cache

This is a very quick but working step, it resets the temporary DNS data. To delete the cache, just enter in the command line ipconfig / flushdns and press Enter.

Method 3: change DNS

Sometimes the default DNS does not work as well, or it is slow or not configured correctly. Google DNS will be the best solution in most cases.

Instructions:

  1. We make a right-click on the Internet connection icon (lower right corner, next to the time).
  2. Select the “Network Control Center …” option and go to the “Change adapter settings” tab.
  3. Double-click to open the active connection and also click on “IP-version 4”.
  4. We set “Set DNS manually” and enter: 8.8.8.8, and in the second line – 8.8.4.4.

Method 4: update the network hardware driver

You can simply download it from the website of the manufacturer of the network card or go to the “Device Manager” and update automatically through the menu available there.

Method 5: go to cable connection

It’s worth trying to switch from Wi-Fi to a wired router connection.

Method 6: clear Battle.net cache

A corrupted cache folder can cause connectivity issues with Call of Duty: Black Ops Cold War. Clearing it can often help eliminate network failures.

What should be done:

  1. Press Ctrl + Shift + Esc to launch the “Task Manager”.
  2. We are looking for the agent.exe process and if it exists, close it through the right mouse click.
  3. Press Win + R and paste% ProgramData% Blizzard Entertainment Battle.net – this will get us into the cache folder.
  4. We delete all content.

Method 7: linking Activision and Blizzard accounts

Users who have not linked their Activision and Blizzard profiles are more likely to see the BLZBNTBGS000003F8 error, as practice shows.

How to link them:

  1. We open the site activision.com
  2. We log into your account and click on the “Profile” button.
  3. Click on the “Link your account with Battle.net” option.

After this step, you will most likely be able to enter the game.

As a last resort, you can still reset the network settings, this option is called “Network Reset” and you can find it through the search. Quite a radical method that requires reconnecting to the internet, but it works. Can be used if none of the above worked.
