DNS Server Not Responding — How to Fix It (Step-by-Step Guide)

The DNS Server Not Responding error means your device cannot communicate with the DNS server. Without DNS, your browser cannot translate domain names into IP addresses.

This issue is usually caused by network problems, DNS misconfiguration, or software interference. In most cases, it can be fixed in minutes.

Quick Fix

• Restart your router and computer.
• Switch to Google DNS (8.8.8.8 / 8.8.4.4).
• Flush your DNS cache.
• Disable VPN or proxy.
• Temporarily turn off antivirus/firewall.
• Reset network settings.

Most DNS errors are local. Changing DNS servers or restarting the network often resolves the issue immediately.

What Does “DNS Server Not Responding” Mean?

The DNS Server Not Responding error appears when your device cannot get a response from the DNS server.

DNS (Domain Name System) translates domain names like google.com into IP addresses.

If the DNS server fails to respond, your browser cannot locate websites.

This does not always mean the website is down. The problem is often on your device or network.

Why This Error Happens

DNS Server Failure

The DNS server you are using may be down or overloaded.

Network Connection Issues

Unstable internet or router problems can block DNS requests.

Incorrect DNS Settings

Manual DNS configuration errors can prevent proper resolution.

Firewall or Antivirus Blocking DNS

Security software may block DNS traffic.

VPN or Proxy Interference

VPNs sometimes use unreliable DNS servers.

Corrupted DNS Cache

Stored DNS records may become outdated or invalid.

Step-by-Step Fixes

1. Restart Your Router and Device

Turn off your router and wait 30 seconds.

Restart your computer and reconnect to the network.

This clears temporary network issues.

2. Change DNS Servers

Switch to reliable public DNS servers.

• Google DNS: 8.8.8.8 / 8.8.4.4
• Cloudflare DNS: 1.1.1.1 / 1.0.0.1

This is one of the most effective fixes.

3. Flush DNS Cache

Clear stored DNS records.

Windows:

ipconfig /flushdns

Mac:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

4. Disable VPN or Proxy

Turn off VPN and proxy services.

They can interfere with DNS resolution.

5. Disable Antivirus or Firewall (Temporarily)

Security software may block DNS connections.

Disable it briefly and test the connection.

6. Reset Network Settings

Reset your network configuration.

Windows:

netsh int ip reset
netsh winsock reset

Restart your computer afterward.

7. Check Network Adapter Settings

Ensure your adapter uses correct DNS settings.

Set DNS manually if needed.

Advanced Troubleshooting

Test DNS with nslookup

nslookup google.com

If no response is returned, DNS is not working.

Try Another Network

Connect to mobile data or another Wi-Fi network.

If it works, the issue is with your original network.

Check ISP DNS Status

Your internet provider’s DNS servers may be down.

Update Network Drivers

Outdated drivers can cause network issues.

Does DNS Server Not Responding Affect SEO?

Yes.

If your site cannot be resolved, search engines cannot crawl it.

This can lead to:

• Indexing issues
• Traffic loss
• Ranking drops

Fix DNS issues quickly to avoid SEO impact.

How to Prevent DNS Issues

• Use reliable DNS providers
• Avoid unstable VPN services
• Keep network drivers updated
• Monitor DNS performance
• Backup DNS configurations

When to Contact Support

Contact your ISP or hosting provider if:

• DNS servers do not respond

• The issue persists across networks

They can verify server-side DNS issues.
