If you're an avid gamer who frequently plays games on Battle.net, then you might have encountered an error code BLZBNTBGS000003F8. This error can be frustrating and can prevent you from playing your favorite games. Fortunately, there are a few simple fixes that you can try to resolve the issue. In this blog post, we'll explore five ways to fix the Battle.net error BLZBNTBGS000003F8.

Repairing Corrupted Game Files


One of the main causes of the BLZBNTBGS000003F8 error is corrupted game files. These are files that have been damaged or altered in some way, preventing the game from running correctly. To fix the issue, you'll need to repair the corrupted game files. Here's how:
  • Step 1: Open the Battle.net app and navigate to the game library.
  • Step 2: Select the game that's causing the error and click on the "Options" button.
  • Step 3: Choose "Scan and Repair" from the drop-down menu.
  • Step 4: Wait for the scan to complete, and then click on the "Repair" button.

This process may take some time, depending on the size of the game and the number of corrupted files. Once the repair process is complete, try launching the game again to see if the error has been resolved.

Updating Network and Graphic Drivers


Outdated network and graphic drivers can also cause connectivity issues and the BLZBNTBGS000003F8 error. To update your drivers, follow these steps:
  • Step 1: Open the Device Manager by right-clicking on the Start button and selecting "Device Manager" from the menu.
  • Step 2: Expand the "Network Adapters" and "Display Adapters" categories.
  • Step 3: Right-click on the adapter that you want to update and select "Update Driver" from the menu.
  • Step 4: Follow the on-screen instructions to complete the driver update.

After updating the drivers, restart your computer and try launching the game again.

Flushing DNS and Renewing IP



DNS (Domain Name System) is a protocol that translates domain names into IP addresses. If the DNS cache is corrupted or outdated, it can cause connectivity issues and the BLZBNTBGS000003F8 error. To flush DNS and renew IP, follow these steps:

  • Step 1: Open the Command Prompt by pressing the Windows key + R and typing "cmd" in the Run dialog box.
  • Step 2: Type "ipconfig /flushdns" and press Enter.
  • Step 3: Type "ipconfig /renew" and press Enter.

After flushing DNS and renewing IP, try launching the game again.

Turning Off Windows Firewall


Windows Firewall is a security feature that can block Battle.net connection, causing the BLZBNTBGS000003F8 error. To turn off Windows Firewall, follow these steps:

  • Step 1: Open the Control Panel by right-clicking on the Start button and selecting "Control Panel" from the menu.
  • Step 2: Click on "System and Security" and then click on "Windows Defender Firewall."
  • Step 3: Click on "Turn Windows Defender Firewall on or off."
  • Step 4: Select "Turn off Windows Defender Firewall (not recommended)" for both private and public networks.

After turning off Windows Firewall, try launching the game again.

Turning Off VPN


VPN (Virtual Private Network) can also interfere with Battle.net connection and cause the BLZBNTBGS000003F8 error. To turn off VPN, follow these steps:

  • Step 1: Open the VPN app on your computer.
  • Step 2: Disconnect from the VPN by clicking on the "Disconnect" button.

After turning off VPN, try launching the game again.



The BLZBNTBGS000003F8 error can be frustrating, but there are several ways to fix it. By repairing corrupted game files, updating network and graphic drivers, flushing DNS and renewing IP, turning off Windows Firewall, and turning off VPN, you can resolve the issue and get back to playing your favorite games on Battle.net. If none of these fixes work, you may need to contact Battle.net customer support for further assistance.
