When you enter a website, your browser asks the DNS server to translate the domain name into an IP address. If the server does not reply, you see the DNS server not responding error. This means your computer cannot reach the right server.

Common Symptoms

• Websites do not load or load very slowly.
• Messages like “Server DNS address could not be found” appear.
• Other devices connect fine, but yours cannot.
• Restarting the router helps only for a short time.

Why Does the DNS Server Not Responding Error Happen?

This error has several possible reasons:

• Weak or unstable internet connection
• Wrong DNS settings on your device
• Busy or down DNS server
• Firewall or antivirus blocking DNS requests
• Old cache data in your browser
• Hosting provider issues with DNS servers

How to Fix DNS Server Not Responding

Here are simple steps you can try:

1. Restart Router and Device

Many small connection problems are solved with a quick restart.

2. Change DNS Settings

Use trusted DNS addresses:

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

3. Clear DNS Cache

• On Windows, open Command Prompt and type:
  ipconfig /flushdns
• Also clear browser cache.

4. Check Security Software

Turn off antivirus or firewall for a short test. If it works, add an exception for DNS.

5. Try a Different Network

Use mobile hotspot or another Wi-Fi. If it works there, your main network has the issue.

6. Contact Hosting Support

If nothing helps, it may be a server-side problem. Reliable providers like Toint Hosting can fix DNS issues quickly.
