The “DNS Server Not Responding” error usually appears when your device is connected to the internet, but websites fail to load. Browsers may show messages like “DNS address could not be found” or “Server IP address could not be found.”
I recently faced this issue on a Windows laptop where the internet was connected, but no websites would open. After checking network settings and testing multiple fixes, I was able to resolve the problem without contacting my internet service provider.
In this article, I’ll explain what this error means, why it happens, and share step-by-step fixes that actually work on both Windows and Android.
What Does “DNS Server Not Responding” Mean?
DNS (Domain Name System) converts website names into IP addresses.
When DNS fails:
- Your device cannot locate websites
- Internet appears connected, but nothing loads
- Browsers show DNS-related errors
This problem is usually caused by network misconfiguration, DNS server issues, or device-level settings.
Common Reasons Behind DNS Server Errors
1. ISP DNS Server Issues
Sometimes your ISP’s DNS servers temporarily stop responding.
2. Incorrect Network Settings
Wrong IP or DNS configuration can block access.
3. Router or Modem Problems
Routers can lose proper DNS communication.
4. VPN, Firewall, or Antivirus Interference
Security tools may block DNS requests.
5. Corrupted DNS Cache
Old DNS records may conflict with new connections.
Step-by-Step Fixes for DNS Server Not Responding
Method 1: Restart Router and Device
This clears temporary network conflicts.
Steps:
- Turn off router and modem
- Wait 30–60 seconds
- Turn them back on
- Restart your device
This alone fixes many DNS issues.
Method 2: Change DNS Server Manually
Switching DNS often resolves the issue instantly.
Recommended DNS servers:
- Google DNS:
8.8.8.8/8.8.4.4 - Cloudflare DNS:
1.1.1.1
Apply DNS manually on your device or router.
Method 3: Flush DNS Cache (Windows)
Steps:
- Open Command Prompt as administrator
- Type:
ipconfig /flushdns - Press Enter
- Restart browser
This removes outdated DNS records.
Method 4: Disable VPN or Proxy Temporarily
VPNs can interfere with DNS requests.
What to do:
- Turn off VPN
- Disable proxy settings
- Test internet again
If internet works, adjust VPN DNS settings.
Method 5: Reset Network Settings
On Windows:
- Go to Settings → Network & Internet
- Select Advanced network settings
- Click Network reset
- Restart PC
On Android:
- Go to Settings → System
- Select Reset options
- Tap Reset Wi-Fi, mobile & Bluetooth
- Reconnect network
This fixes misconfigured settings.
Method 6: Disable Antivirus or Firewall Temporarily
Some antivirus programs block DNS traffic.
- Disable antivirus briefly
- Test internet
- Re-enable antivirus after testing
Never leave security software disabled permanently.
Method 7: Update Network Drivers (Windows)
Outdated drivers can cause DNS errors.
Steps:
- Open Device Manager
- Update network adapter
- Restart system
This is especially important after Windows updates.
Why DNS Errors Happen Frequently on Public Wi-Fi
Public networks often:
- Use unstable DNS servers
- Restrict certain domains
- Require login pages
Try opening any website to trigger the login portal.
FAQs
Is DNS Server Not Responding a serious issue?

Only if the problem persists after trying all fixes.
Final Thoughts
The DNS Server Not Responding error can block internet access even when the connection appears fine. In most cases, the problem is related to DNS settings or temporary network issues.
From my experience, switching to Cloudflare or Google DNS and restarting the router fixed the issue immediately. Try the steps one by one, and internet access should return quickly.
