  3. If you cannot play the game over a wired connection – change the channel of the router to the one that’s least used or if you are on 5Ghz, change it to 2.4Ghz, or the other way around.
  4. Resetting the Windows Network has also proven to resolve the error for other games. In order to do it, press Windows + S and type Network Reset. Follow the option from the search and click on Reset now.

  6. Press Windows Key + R and type msconfig, hit Enter
  7. Go to the Services tab
  8. Check Hide all Microsoft services
  9. Now, click Disable all
  10. Go to the Startup tab and click on Open Task Manager
  11. Disable one task at a time and restart the system.
  12. 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.
  13. Update the firmware of the network hardware.
  14. If you have the option, try to play the game over a different ISP or your mobile hotspot. If the game works without Error BLZBNTBGS000003F8 appearing, your NAT type might be restricted.
