The Domain Name System (DNS) helps users access websites on the internet through web browsers. It is a directory that translates domain names or hostnames into Internet Protocol (IP) addresses. Show
Sometimes, the web browser cannot connect to the site and shows a “DNS server not responding” error message instead. This error often happens because the DNS server fails to map hostnames to IP addresses correctly. There are many possible reasons for this error, from misconfigured network adapters to incorrect DNS server addresses. This article will go over 11 potential solutions to solve the “DNS server not responding” issue on Windows and macOS. We will also explain several common causes for this error message. What Does “DNS Server Not Responding“ Mean?The “DNS server not responding” error message means that the DNS of the domain you want to reach is unavailable or your browser cannot connect to the internet. Possible fixes include restarting your router or modem, checking for network issues, and updating your browser. DNS servers play an essential role in accessing web addresses online. With the proper DNS configuration, the server automatically retrieves an IP address whenever a user enters a URL into a browser. The “DNS server not responding” error usually lies on the user’s end. Often, there is no need to get technical support to fix this error. It is generally easy to find its cause and resolve it immediately. Fixing this issue can be as simple as troubleshooting your network problems or connecting with a different device.

Troubleshoot Network ProblemsRunning network diagnostics is the first step to fix “the DNS server isn’t responding” error. This method can help diagnose and troubleshoot all detected network issues and errors without much hassle. Here’s how to run network diagnostics for both Windows and Mac computers. Run Windows Network Diagnostics Follow the steps to run network diagnostics on Windows 10:
Configure Wireless Diagnostics on Mac Here’s how to run wireless diagnostics on macOS:
If this method does not fix the DNS servers problem, proceed to the next step. 2. Connect With a Different DeviceTry connecting a different device to the same home network and accessing the site you’re having trouble with. If the second device can access the web page using the same network, then the problem is with your primary device. However, if you still can’t visit the website with other devices connected to the same network, it could suggest that your router might be the issue. Using other connections, such as mobile data, can also help ensure that the connection failing issue is not on the site’s end. 3. Switch to Another Web BrowserAnother simple solution to try when solving the “DNS server not responding” issue is to visit the website from a different web browser. For instance, if your primary browser is Mozilla Firefox, try to access the web page from other browsers, such as Microsoft Edge and Google Chrome. If this method turns out to be fruitful, then update your default browser to the newest version or reinstall it completely. However, if the “DNS server not responding” message appears once again, the browser is not the source of the connection problem. 4. Restart the PC in Safe ModeAn operating system that isn’t correctly working can result in the “DNS server not responding” error message. To figure out whether this problem makes the DNS server unavailable, you’ll need to restart your computer in safe mode – a stripped-down version of your operating system that can limit the files and resources used for running your device. Here are steps to start a computer in safe mode on Windows:
If you’re using a Mac, here’s how to start up your computer in safe mode:
If your network connection works in safe mode, it means that third-party software might be causing the “DNS server not responding” issue. To resolve this, you’ll need to find and delete the application from your PC. 5. Restart Modem or RouterA modem or router that isn’t properly functioning can also be the cause of why a DNS server isn’t responding and the connection is failing. Therefore, consider restarting your modem or router to clear the cache, potentially fixing the DNS servers problem. Press the power button of your router or modem and unplug its power cable from the power outlet. Wait for at least 30 seconds before pressing the power button again to restart it. If restarting your modem or router doesn’t work, try to reset it to its default settings. Check the instruction manual of the device for steps to reset your modem or router. 6. Deactivate Antivirus and FirewallAntivirus and firewall programs aim to protect your device from malicious software. However, these tools can also block your internet connection. Attempt to temporarily deactivate your antivirus and firewall programs to check whether or not they’re the cause of the “DNS server is not responding” error. To access the antivirus and firewall settings on Windows, select the Start menu and click Settings -> Update & Security -> Windows Security -> Virus & threat protection. If you use a Mac computer, go to System Preferences -> Security & Privacy -> Firewall. After deactivating your antivirus and firewall programs, rerun the network diagnostics and open the website again from your browser. If this solves the problem, update or reconfigure the antivirus and firewall programs before reactivating them. 7. Disable Other ConnectionsAnother solution to resolve the “DNS server not responding” issue is to disable unused connections on your device. Follow these steps to disconnect additional network connections on Windows:
Here’s how to disable other network connections on Mac:
After disabling all unused connections, restart your browser and try re-accessing the website. 8. Change the DNS Server AddressIf the website cannot be accessed after the previous solutions, try to change your DNS server address. Your home network is configured to obtain a DNS server address automatically from your internet service provider (ISP). However, if your ISP’s DNS server isn’t responding, the configured DNS server is incorrect or does not exist, the internet service will stop working as well. To temporarily resolve this problem, change your DNS settings and use a different DNS address. Doing so allows your browser to be still able to load any websites on the internet. Fortunately, many services such as Cloudflare and Google Public DNS offer DNS addresses to use for free. To set up other DNS servers on Windows, follow these steps:
Here are the steps to change the DNS server address on Mac:
Reset your internet connection and see if “the DNS server isn’t responding” problem is resolved. 9. Flush DNS CacheAnother solution in order to fix DNS servers connection issues is to flush the DNS cache. Clearing the router cache might help make the DNS work properly. Here are the steps to flush DNS cache files on Windows:
The steps to flush DNS cache files on Mac are also relatively simple, but it’s crucial to run the correct command prompt based on your current operating system version. On your Mac, open the Terminal by pressing F4 and entering the “terminal” in the Launchpad’s search box. Once the app is opened, run the command that suits your version of macOS. On macOS Big Sur, enter the following command: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder To flush DNS cache on macOS Catalina, run this in the command prompt: sudo killall -HUP mDNSResponder Run this command to clear your DNS cache on macOS Mojave: sudo killall -HUP mDNSResponder Flush DNS cache on macOS High Sierra with this command : sudo killall -HUP mDNSResponder For macOS Sierra, Mac OS X El Capitan, X Mavericks, X Mountain Lion, or X Lion, run the following command: sudo killall -HUP mDNSResponder If you’re running Mac OS X Yosemite, input this command: sudo discoveryutil udnsflushcaches On Mac OS X Snow Leopard, run the command to flush DNS cache : sudo dscacheutil -flushcache If you’re using Mac OS X Leopard and below, enter this command: sudo lookupd -flushcache After running the commands above, the network adapter will refresh its DNS configuration. 10. Disable IP Version 6 (IPv6)Internet Protocol Version 6 (IPv6) is the latest version of the internet protocol that identifies devices on the internet and a local network. However, IPv6 can also cause the “DNS server is not responding” issue. Therefore, consider disabling IPv6 if the previous solutions still don’t solve the problem. To disable IPv6 on Windows, do the following:
Here are the steps to turn off IPv6 on your Mac:
If the off option is not available in the Configure IPv6 drop-down menu, try to disable IPv6 with the command line. To disable IPv6 on a wireless connection, open the Terminal app on your Mac and run the following command: networksetup -setv6off Wi-Fi If you want to deactivate IPv6 on an ethernet connection, use this command instead: networksetup -setv6off Ethernet It’s also possible to disable IPv6 on a wireless and ethernet connection together by entering the following command: sudo killall -HUP mDNSResponder 0 Ensure to restart your device and connect to the internet again to check whether the “DNS server not responding” issue is resolved. 11. Update the Network Adapter DriverAn outdated network adapter driver can also be why the DNS servers failed issue appears on your Windows computer. There are two options to update your network adapter driver – either manually or automatically. Manually updating a network adapter driver can be challenging for beginners unfamiliar with driver software. Therefore, it’s recommended to automate it with a tool like Driver Easy, which can help download and install the correct drivers for your system. Keep in mind that it’s essential to create a system restore point in your Windows before using the free version of Driver Easy. Doing so lets your computer turn to its previous state if an unexpected event happens. To automatically update your network adapter driver with Driver Easy, follow these steps:
