To fix the net::ERR_NAME_NOT_RESOLVED error, start by checking your internet connection and ensuring your DNS settings are correctly configured. This error typically occurs when your browser cannot resolve the domain name into an IP address, preventing access to the website.
What Causes the net::ERR_NAME_NOT_RESOLVED Error?
Understanding the root causes of the net::ERR_NAME_NOT_RESOLVED error is crucial for effective troubleshooting. This error can arise due to several factors:
- DNS Configuration Issues: Incorrect DNS settings can prevent your device from resolving domain names.
- Network Connectivity Problems: A weak or unstable internet connection can lead to DNS resolution failures.
- Browser Cache and Cookies: Corrupt or outdated cache and cookies may interfere with DNS resolution.
- Firewall or Security Software: Overly restrictive settings might block DNS requests.
By pinpointing the cause, you can apply the appropriate solution to resolve this issue.
How to Fix net::ERR_NAME_NOT_RESOLVED Error?
1. Check Your Internet Connection
Before diving into technical fixes, ensure your internet connection is stable:
- Restart your router or modem.
- Try connecting to a different network.
- Test other devices on the same network to see if they encounter the same issue.
2. Clear Browser Cache and Cookies
Corrupted cache and cookies can cause the net::ERR_NAME_NOT_RESOLVED error. Follow these steps to clear them:
- Google Chrome: Go to Settings > Privacy and Security > Clear Browsing Data. Select "Cookies and other site data" and "Cached images and files," then click "Clear data."
- Mozilla Firefox: Open Options > Privacy & Security > Cookies and Site Data > Clear Data.
- Microsoft Edge: Navigate to Settings > Privacy, search, and services > Clear browsing data > Choose what to clear.
3. Flush DNS Cache
Flushing the DNS cache can help resolve this error by clearing outdated DNS records:
- Windows: Open Command Prompt as an administrator and type
ipconfig /flushdns, then press Enter. - MacOS: Open Terminal and type
sudo killall -HUP mDNSResponder, then press Enter. - Linux: Open Terminal and type
sudo systemd-resolve --flush-caches, then press Enter.
4. Change DNS Servers
Switching to a reliable DNS server can improve domain name resolution:
- Google DNS: 8.8.8.8 and 8.8.4.4
- Cloudflare DNS: 1.1.1.1 and 1.0.0.1
To change DNS settings:
- Windows: Go to Control Panel > Network and Sharing Center > Change adapter settings. Right-click your network connection, select Properties, then Internet Protocol Version 4 (TCP/IPv4) > Properties. Enter the preferred DNS server addresses.
- MacOS: Go to System Preferences > Network. Select your network, click Advanced, then DNS. Add the new DNS server addresses.
- Linux: Edit the
/etc/resolv.conffile to include the new DNS server addresses.
5. Disable Firewall and Security Software Temporarily
Sometimes, firewalls or security software can block DNS requests. Temporarily disable them to see if it resolves the issue. Remember to re-enable them afterward to maintain your device’s security.
