The "ERR_NAME_NOT_RESOLVED" error when using a VPN typically means your browser cannot resolve the domain name into an IP address, indicating a DNS (Domain Name System) resolution issue. When you connect to a VPN, your device usually relies on the VPN's DNS servers instead of your local ISP's DNS. If the VPN's DNS servers are malfunctioning, unreachable, or misconfigured, you will see this error. Common causes for this error when using a VPN include:
- The VPN server's DNS servers are down, slow, or having connectivity problems.
- Misconfigured VPN settings causing DNS resolution to fail.
- Conflicting network configurations on your device, such as multiple active network connections interfering with each other.
- Your firewall or antivirus software blocking DNS requests via the VPN.
- Cached DNS entries on your device becoming outdated or corrupted.
Typical ways to fix this issue when using a VPN are:
- Ensuring your VPN is properly set up and connected.
- Switching to reliable public DNS servers like Google's (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1) in your VPN or network settings.
- Flushing your device's DNS cache to clear outdated IP address entries.
- Resetting or temporarily disabling your firewall or antivirus to check if they are blocking DNS requests.
- Disabling other network connections, like mobile data, that may conflict with the VPN.
- Testing the connection without the VPN to confirm it is the source of the DNS problem.
These approaches can help resolve the ERR_NAME_NOT_RESOLVED error related to DNS issues encountered when using a VPN.
