A VPN can sometimes cause the ERR_NAME_NOT_RESOLVED error, which occurs when the DNS server fails to resolve a domain name. This error might arise if the VPN is misconfigured or if there’s a conflict with the DNS settings. Understanding how a VPN interacts with DNS can help you troubleshoot and resolve this issue effectively.
What Causes ERR_NAME_NOT_RESOLVED When Using a VPN?
How Does a VPN Affect DNS Resolution?
When you connect to a VPN, your internet traffic is routed through a secure server, often in a different location. This setup can affect DNS resolution because:
- DNS Servers: VPNs may use their own DNS servers, which can conflict with your default settings.
- Network Configuration: Changes in network settings can disrupt DNS resolution if not configured correctly.
- Server Location: The VPN server’s location might affect the speed and reliability of DNS queries.
Why Would a VPN Cause ERR_NAME_NOT_RESOLVED?
Several factors can lead to the ERR_NAME_NOT_RESOLVED error while using a VPN:
- Incorrect DNS Settings: The VPN might configure DNS settings that aren’t compatible with your network.
- VPN Server Issues: The server you’re connected to may be experiencing technical difficulties.
- Software Conflicts: Other software, such as antivirus or firewall programs, might interfere with DNS settings.
How to Fix ERR_NAME_NOT_RESOLVED with a VPN
What Steps Can You Take to Resolve the Error?
If you’re encountering this error, consider the following troubleshooting steps:
- Change DNS Settings: Switch to a public DNS service like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).
- Restart Your Router: Power cycling your router can resolve temporary network issues.
- Update VPN Software: Ensure your VPN software is up-to-date to avoid compatibility issues.
- Switch VPN Servers: Try connecting to a different server location to see if the issue persists.
- Disable Security Software: Temporarily disable antivirus or firewall software to check for conflicts.
How to Change DNS Settings?
Changing your DNS settings can often resolve DNS-related errors:
- Windows: Go to Control Panel > Network and Sharing Center > Change adapter settings. Right-click on your network, select Properties, and then select Internet Protocol Version 4 (TCP/IPv4). Enter the preferred DNS server addresses.
- Mac: Go to System Preferences > Network. Select your network and click Advanced. Go to the DNS tab and add the new DNS server addresses.

How Does a VPN Protect My Online Privacy?
A VPN encrypts your internet traffic, making it difficult for third parties to monitor your online activities. This encryption helps protect your privacy and secures sensitive data from potential hackers.
Can I Use a Free VPN to Avoid ERR_NAME_NOT_RESOLVED?
While free VPNs are available, they often come with limitations such as slower speeds, fewer server options, and potential security risks. A paid VPN service typically offers better reliability and support for resolving errors like ERR_NAME_NOT_RESOLVED.
What Are the Best VPNs for Reliable DNS Resolution?
Some of the most reliable VPNs for DNS resolution include ExpressVPN, NordVPN, and CyberGhost. These services offer robust DNS leak protection and a wide range of server locations.
Is It Safe to Change DNS Servers?
Yes, changing DNS servers to reputable services like Google DNS or Cloudflare DNS is generally safe and can improve your internet speed and security.
How Do I Know If My VPN Is Causing DNS Errors?
To determine if your VPN is causing DNS errors, disconnect from the VPN and try accessing the website again. If the site loads without issues, the VPN may be the cause.
Conclusion
Understanding how a VPN can cause the ERR_NAME_NOT_RESOLVED error is crucial for maintaining a smooth online experience. By addressing DNS settings, server issues, and software conflicts, you can effectively resolve this error and ensure reliable internet connectivity.
