How to Fix the ‘ERR_NAME_NOT_RESOLVED’ Error: A Comprehensive Guide

The ‘ERR_NAME_NOT_RESOLVED’ error typically occurs when your browser is unable to resolve a website’s domain name into its corresponding IP address. This issue is often linked to DNS-related problems. Below are the main causes and solutions for this error.

Common Causes of ‘ERR_NAME_NOT_RESOLVED’:

1. DNS Issues: Misconfigured or unresponsive DNS servers can lead to domain resolution failures.
2. Network Configuration Problems: Incorrect IP settings or conflicts within your network can disrupt DNS communication.
3. Corrupted Cache: If your browser’s cache contains outdated or damaged DNS records, the resolution may fail.
4. Firewall or Antivirus Blockage: Security software can sometimes block DNS requests, causing the error.
5. Website-Specific Issues: The website itself could be experiencing DNS issues, preventing it from being resolved properly.

How to Fix the ‘ERR_NAME_NOT_RESOLVED’ Error:

1. Check Your Internet Connection: Start by ensuring your internet connection is stable. If other websites load without issues, the problem is likely specific to the site you’re trying to visit.
2. Clear Your Browser Cache: A corrupted browser cache can cause outdated DNS records to persist. Clear your browser’s cache and cookies to remove any old data.
3. Change Your DNS Server: The issue might lie with your DNS provider. Switch to a reliable DNS service, such as Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1), which tend to be faster and more reliable.
4. Flush the DNS Cache: Flush the local DNS cache to remove any outdated DNS records. For Windows, open Command Prompt and type ipconfig /flushdns. On macOS, open Terminal and type sudo killall -HUP mDNSResponder.
5. Disable Your Security Software: Firewalls or antivirus programs can sometimes block DNS requests. Temporarily disable them to see if the error resolves.
6. Restart Your Router: A simple router restart can often resolve network configuration issues and reset the DNS settings, which might fix the error.
7. Try Another Browser: The problem may be browser-specific. Try accessing the website in a different browser to rule out any browser-related issues.

By following these troubleshooting steps, you can resolve the ‘ERR_NAME_NOT_RESOLVED’ error and ensure smooth browsing.
