How to Fix DNS Server Not Responding

DNS server errors prevent your device from connecting to websites even when your internet connection works. This happens when your DNS resolver can't translate domain names into IP addresses.

  1. Restart your network connection. Disconnect from Wi-Fi and reconnect, or unplug your ethernet cable for 10 seconds and plug it back in. On Windows, go to Settings > Network & Internet > Status > Network reset. On Mac, turn Wi-Fi off and on in System Preferences > Network.
  2. Flush your DNS cache. Open Command Prompt as administrator on Windows and run 'ipconfig /flushdns'. On Mac, open Terminal and run 'sudo dscacheutil -flushcache'. On Chrome, go to chrome://net-internals/#dns and click 'Clear host cache'.
  3. Change your DNS server settings. Go to Network Settings and change DNS servers to Google's (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1 and 1.0.0.1). On Windows, go to Control Panel > Network and Sharing Center > Change adapter settings > right-click connection > Properties > Internet Protocol Version 4. On Mac, go to System Preferences > Network > Advanced > DNS.
  4. Disable antivirus and firewall temporarily. Turn off Windows Defender Firewall by going to Control Panel > System and Security > Windows Defender Firewall > Turn Windows Defender Firewall on or off. Disable antivirus protection temporarily through its settings. Test internet connection, then re-enable immediately.
  5. Reset network settings to defaults. On Windows, open Command Prompt as administrator and run 'netsh winsock reset' followed by 'netsh int ip reset'. Restart your computer. On Mac, go to System Preferences > Network, select your connection, click Advanced > TCP/IP > Renew DHCP Lease.
  6. Update network adapter drivers. Right-click Start button and select Device Manager on Windows. Expand Network adapters, right-click your adapter, and select 'Update driver'. On Mac, check System Preferences > Software Update for macOS updates that include driver updates.
  7. Restart your router and modem. Unplug your modem and router for 30 seconds. Plug in the modem first and wait for all lights to stabilize. Then plug in the router and wait for full startup. Test your connection after all devices finish booting.
