If the servers are functioning desirably, the problem can be at your end. In that case, we have several solutions that can potentially resolve the error, but you should note that these are not universal solutions, meaning it may work for one user, but fail for the other. Since the system specifications and hardware configuration of each user is different, darting the exact cause of the problem is impossible. However, the below solutions seems to work for most users.

  1. It is always recommended that you play the game over Powerline, Ethernet, or MoCA rather than wireless connections. Cable connections, fiber, and DSL are best for online games.

  2. Resetting the network hardware such as modem or router is known to resolve issues such as this. A number of users have been able to resolve the Black Ops Cold War error code BLZBNTBGS00000BC6 by resetting the router.
  3. Try terminating all programs running in the background. We ideally want to close programs that may be using the internet, but just to be more comprehensive in addressing any other problems caused by third-party programs, we will suspend all programs. Here are the steps you can follow.
    • Press Windows Key + R and type msconfig, hit Enter
    • Go to the Services tab
    • Check Hide all Microsoft services
    • Now, click Disable all
    • Go to the Startup tab and click on Open Task Manager
    • Disable one task at a time and restart the system.
  4. Switch to Google DNS. Here are the steps.
    • Press Windows Key + I and select Network & Internet
    • Click on Change adapter options
    • Right-click on your connection and select Properties
    • Select Internet Protocol Version 4 (TCP/IPv4) and click on Properties
    • Toggle Use the following DNS server addresses and enter primary as and secondary as
    • Save the changes.
  5. Flush DNS using Command Prompt. Here are the steps.
    • Type cmd in the Windows Search and select Run as administrator from the right panel
    • Copy and paste or type ipconfig /release, hit Enter
    • Copy and paste or type ipconfig /renew, hit Enter
    • Copy and paste or type ipconfig /flushdns, hit Enter (after hitting Enter after each command, wait for the process to complete).
  6. While you are playing the game, do not use any other device connected to the same network. Also, terminate bandwidth-intensive tasks such as Netflix, YouTube, or other video streaming services, file transfer (torrents), etc.

He is caught in a loop between writing about games and playing them. It's a vicious cycle. Although he's biased towards PC, you can occasionally find him on the PS5. He does not own an Xbox Consoles but plans on getting one soon.


  1. Pathetic, today is 18.02.2021 00:50 am and this happening to mw for the first time. Another trick to make People play retarded Cold war instead of modern warfare which is 100 Times better, or just another bug they release. Since infonity Ward gave control to treyarch they funkcją up everything to force People play the worst game ever.

    This is a joke, they should get HUGE cash penalty.

  2. lol really ? Thats all u can say? Telling me its a Client prob? U arent able to change ur income money of bullshit shop items to performance stable products. Greta would say How dare are u ? I am saying Blizzard never will change anything. Just take the money and tell the world how Great they are. It is a kind of bullshit what u are doing. Telling me it depends on power… LOL What result should that be? Nothing really notihng wont help ya to fix it. Just Bliizard or these small unknown like Raven or Infinty can change I am laughing bout their way of life. Also bout these crying kids (age 12-60) who arent able to find to do instead of crying through discord twitter and all these chanels.
    Like Cyberpunk2077. Go OFF and make it correct.
