Disable Antivirus and Firewall

Sometimes, antivirus programs or firewalls can interfere with the proper functioning of Diablo 4 and lead to Error Code 30008.

These security measures may mistakenly identify the game’s network connections as a threat and block them.

To resolve this issue, you can temporarily disable your antivirus and firewall software. Here’s how to do it:

Windows Defender Firewall

• Press the Windows key + R to open the Run dialog box.
• Type “control firewall.cpl” and press Enter.
• In the Windows Defender Firewall window, click on “Turn Windows Defender Firewall on or off” in the left pane.
• Select the option “Turn off Windows Defender Firewall” for both private and public networks.
• Click “OK” to save the changes and disable the firewall.

Third-Party Antivirus Software

• Locate the antivirus program’s icon in the system tray or the taskbar.
• Right-click on the icon to access the context menu.
• Look for options like “Disable,” “Pause protection,” or “Suspend.”
• Choose the appropriate option to disable the antivirus temporarily.
• Confirm any prompts or dialog boxes that appear.

Remember to enable your antivirus and firewall once you have finished playing Diablo 4.

Disabling these security measures leaves your computer vulnerable to potential threats, so it’s essential to re-enable them afterward.

Flush DNS Cache

DNS (Domain Name System) cache stores information about previously visited websites and their corresponding IP addresses.

Outdated or corrupted DNS cache entries can sometimes lead to connectivity issues, including Diablo 4 Error Code 30008.

Flushing the DNS cache can help resolve this problem.

Here’s how you can do it:

• Open the command prompt on your computer.
• Press the Windows key, type “Command Prompt,” and click on the corresponding search result.
• In the command prompt window, type the following command and press Enter: “ipconfig /flushdns”
• Wait for the DNS catching to complete.
• You should see a message confirming that the DNS cache has been flushed successfully.
• Close the command prompt and relaunch Diablo 4 to check if the error persists.

Flushing the DNS cache removes any outdated entries and forces your computer to retrieve the most up-to-date IP addresses for the game’s servers.

This can help resolve connectivity issues and potentially fix Error Code 30008.

Check Your NAT Type

Network Address Translation or (NAT) is a feature used in routers to translate private IP addresses to public IP addresses and vice versa.

Different NAT types can affect online gaming experiences, including Diablo 4.

It’s recommended to have an “Open” NAT type for the best connectivity.

Here’s how you can check your NAT type:

• Open your web browser and enter your router’s IP address in the address bar.
• You can usually find this information in the router’s documentation or on the back of the router itself.
• Log in to your router’s administration panel using the provided credentials.
• Look for the NAT or Port Forwarding settings.
• The location of these settings can vary depending on your router’s make and model.
• Find the NAT type or NAT filtering option and check the current setting.
• If your NAT type is not “Open,” consult your router’s documentation or the manufacturer’s website for instructions on how to change it to “Open.”
• This may involve setting up port forwarding or enabling Universal Plug and Play (UPnP) on your router.

Having an “Open” NAT type helps ensure a smoother connection to Diablo 4 servers and reduces the likelihood of encountering Error Code 30008.

Use a Public DNS Server (Google DNS)

Sometimes, using a public DNS server like Google DNS can help improve your network connectivity and resolve Error Code 30008.

To change your DNS server settings to Google DNS, follow these steps:

• Press the Windows key + R to open the Run dialog box.
• Type “ncpa.cpl” and press Enter to open the Network Connections window.
• Right-click on your active network connection and select “Properties.”
• In the Network Connection Properties window, scroll down and double-click on “Internet Protocol Version 4 (TCP/IPv4).”
• In the next window, select the option “Use the following DNS server addresses.”
• Enter the following DNS server addresses:
  (a) Preferred DNS server: 8.8.8.8
  (b) Alternate DNS server: 8.8.4.4
• Click “OK” to save the changes and close all open windows.
• Relaunch Diablo 4 and check if the error persists.

Using Google DNS can potentially improve your network’s stability and reduce the occurrence of Error Code 30008 by providing faster and more reliable DNS resolution.
