4. Fix Error Code 34202 in Diablo 4 by Configuring Your Network Devices

Sometimes, your default DNS server address can end up filtering/blocking connections to specific servers. Switching to common DNS servers such as Google’s (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1 and 1.0.0.1) could help. Then you can also try releasing and renewing your IP and flushing your DNS to resolve any network conflicts. Lastly, check the reliability of your internet connection by running Command Prompt. Once opened, type in “ping google.com -t.” (without quotes). If the time exceeds 100ms or there is a Request timed out message, you’re having connection issues.

5. Disable Proxy or VPN

If you use a VPN or proxy server to hide your IP address, you might run into some problems when accessing the server. That’s why you should try disabling your VPN or proxy servers to ensure a smooth and secure gaming experience.
