Introduction
DNS server not responding is a common internet error that prevents websites from loading even though your device appears to be connected to the internet. This issue can occur on Windows, macOS, and even some mobile devices due to incorrect DNS settings, router problems, or temporary network issues.
Fortunately, most DNS problems can be resolved in just a few minutes. Follow the solutions below in order until your internet connection is restored.
Why Does the DNS Server Stop Responding?
Common causes include:
- Incorrect DNS settings
- Router or modem issues
- ISP DNS server problems
- Outdated network drivers
- Firewall or antivirus interference
- Temporary Windows network glitches
Fix 1: Restart Your Router
Turn off your router for 30 seconds before turning it back on. Once all the lights become stable, test your internet connection again.
Fix 2: Restart Your Computer
A simple restart clears temporary networking issues that may be causing the DNS error.
Fix 3: Change Your DNS Server
If your ISP’s DNS server isn’t responding, switch to a public DNS service.
Google DNS:
- 8.8.8.8
- 8.8.4.4
Cloudflare DNS:
- 1.1.1.1
- 1.0.0.1
Fix 4: Flush the DNS Cache
On Windows:
- Open Command Prompt as Administrator.
- Type:
ipconfig /flushdns - Press Enter.
- Restart your browser and test again.
Fix 5: Disable VPN or Proxy
A VPN or proxy server can interfere with DNS requests. Disable them temporarily and check if websites load correctly.
Fix 6: Update Network Drivers
Open Device Manager, locate your network adapter, and install any available driver updates.
Fix 7: Disable Antivirus or Firewall Temporarily
Some security software may block DNS requests. Disable it briefly to test whether it’s causing the issue, then re-enable it after troubleshooting.
Fix 8: Run the Windows Network Troubleshooter
Go to:
Settings → System → Troubleshoot → Other troubleshooters → Network & Internet
Run the troubleshooter and follow the suggested fixes.
Fix 9: Contact Your Internet Service Provider
If DNS server not responding continues after trying the fixes above, your ISP may be experiencing DNS outages or connection problems. Contact their support team for assistance.
