How to Fix DNS Server Not Responding: Complete Guide for All Devices
The DNS server is a critical part of the internet, acting as a phone book that translates domain names into IP addresses. Every time you enter a website address, your device relies on the DNS server to find it. If your browser cannot connect to a DNS server, you may encounter the frustrating error message: “DNS server not responding.” While this issue can feel alarming, it is usually not caused by a major system failure. Instead, it often stems from misconfigured settings, network problems, or temporary issues with your Internet Service Provider (ISP).
This guide will show you how to fix DNS server not responding errors across all major devices, including Windows PCs, Macs, Android and iOS devices, and gaming consoles. By following these steps, you can restore internet connectivity quickly and prevent similar problems in the future.
Understanding the DNS Server Not Responding Error
What DNS Servers Do
DNS servers are the backbone of internet navigation. When you type a website URL, your browser does not directly connect to that website. Instead, it contacts a DNS server to translate the human-readable address into a numerical IP address. Without a functioning DNS server, websites cannot load, resulting in errors or blank pages.
Beyond basic browsing, DNS servers also handle email routing, cloud applications, and streaming services. Any disruption in DNS can affect multiple applications simultaneously, making it essential to understand how they work when troubleshooting connectivity issues.
Common Causes of DNS Server Errors
Several issues can trigger the DNS server not responding error:
- Incorrect DNS settings – Changes made manually or after updates can misconfigure your DNS.
- Network adapter problems – Outdated drivers or misconfigured settings can prevent proper DNS communication.
- ISP-related issues – Sometimes, your ISP’s DNS server is down or overloaded.
- Firewall or antivirus interference – Security software can block DNS queries.
- Malware or VPN conflicts – Malicious software or VPN misconfigurations may prevent proper DNS resolution.
Understanding these causes is the first step in effectively resolving the error and restoring internet access.
Symptoms of DNS Server Issues
Common signs of DNS server problems include:
- Websites failing to load completely
- Receiving repeated DNS server not responding messages
- Slow internet speed or intermittent connectivity
- Errors affecting specific websites rather than all sites
Recognizing these symptoms helps you take action quickly before the issue escalates.
How to Fix DNS Server Not Responding on Windows
Restart Your Router and Computer
One of the simplest ways to fix DNS server not responding issues is by restarting your network devices. Turn off your modem and router, wait 2–3 minutes, and then power them back on. Restart your Windows PC afterward to refresh network settings. This often resolves temporary glitches without any complicated steps.
Check Network Connections
Verify that your cables, Wi-Fi adapters, and network settings are functioning correctly. Loose Ethernet cables or weak Wi-Fi signals can mimic DNS errors. Windows’ built-in network troubleshooter can detect and fix common issues automatically.
Change DNS Server Settings
Switching to a reliable public DNS server, such as Google DNS (8.8.8.8, 8.8.4.4) or OpenDNS (208.67.222.222, 208.67.220.220), can resolve recurring problems. Update your network adapter settings with these DNS addresses to bypass faulty ISP servers.
Temporarily Disable Firewall or Antivirus
Security software can interfere with DNS queries. Temporarily disabling your antivirus or firewall can help determine if they are causing the error. If internet connectivity returns, configure your security software to allow DNS traffic.
Update Network Drivers
Outdated or corrupted network drivers can cause DNS server not responding errors. Open Device Manager, check for driver updates, and install the latest versions to ensure smooth communication between your PC and DNS server.
How to Fix DNS Server Not Responding on Mac
Restart Your Mac and Router
Just like on Windows, restarting your Mac and router can often solve DNS issues. This refreshes network configurations and resolves temporary problems.
Change DNS Settings
Open Network Preferences, select your active connection, and navigate to the DNS tab. Add reliable DNS servers, such as Google DNS or Cloudflare (1.1.1.1), then reconnect to the internet. This often stabilizes your connection.
Flush DNS Cache
Open Terminal and run the command:
sudo killall -HUP mDNSResponder
This clears the DNS cache, forcing your Mac to request fresh DNS records from the server.
Check Security Software
Ensure that antivirus programs, VPNs, or firewalls are not blocking DNS connections. Adjust settings to allow normal DNS traffic while keeping your system secure.
How to Fix DNS Server Not Responding on Mobile Devices
Android Devices
Go to Wi-Fi settings, select your network, and manually change the DNS settings to Google DNS or Cloudflare. This can solve connectivity issues without affecting your device’s overall performance.
iOS Devices
On iPhone or iPad, open Wi-Fi settings, tap your network, and update DNS manually. Using a trusted public DNS server can bypass default ISP servers and fix errors quickly.
How to Fix DNS Server Not Responding on Gaming Consoles & Smart TVs
On consoles like PlayStation, Xbox, or on smart TVs, go to network settings and change the DNS manually. Using reliable DNS servers reduces connectivity interruptions during online gaming or streaming.
Advanced Troubleshooting Steps
If standard fixes fail, try these advanced methods:
- Reset TCP/IP Stack on Windows – Open Command Prompt and run:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
- Use nslookup to Diagnose – Test if your DNS server resolves addresses properly.
- Check for DHCP Issues – Ensure your router assigns IP addresses correctly.
- Update Firmware – Keep your router firmware up to date.
These steps can resolve persistent or complex DNS issues that standard methods cannot fix.
Preventing DNS Server Errors in the Future
- Regularly update your router firmware
- Use trusted DNS servers like Google DNS or Cloudflare
- Avoid unnecessary changes to network settings
- Scan for malware frequently
- Monitor for ISP outages
Following these precautions ensures smooth and uninterrupted internet performance.
Conclusion
The DNS server not responding error is common but fully fixable. By understanding DNS functionality and systematically applying troubleshooting steps—restarting devices, updating drivers, changing DNS servers, and clearing DNS caches—you can restore internet connectivity across all platforms. Regular maintenance and smart configuration reduce the risk of recurring errors, ensuring a smooth online experience.
Frequently Asked Questions
What is a DNS server, and why does it stop responding?
DNS servers translate domain names into IP addresses. Misconfigured settings, ISP issues, or security software can cause them to stop responding.
Can changing DNS servers improve internet speed?
Yes. Public DNS servers like Google DNS or Cloudflare can provide faster response times.
Is it safe to use public DNS servers?
Absolutely. Trusted public DNS servers are secure and widely used globally.
Why do some websites load while others don’t during DNS errors?
Partial DNS resolution may occur due to cached or outdated records. Changing DNS servers usually fixes this.
How do I know if the problem is with my device or ISP?
Test multiple devices on the same network. If all devices fail, the issue is likely with your ISP.
