In simple words, a DNS or Domain Name Server is a translator that translates hostnames that are alphanumeric into IP addresses. Let us understand how it works in detail.

First of all, when you enter your web address or hostname in the address bar of your web browser, it is sent to a nearby DNS server via your router, where it gets translated into a numeric IP address. During this translation process, if anything went wrong, the user will get notified by an error message on their web browser page stating “DNS server is not responding”. i.e your web browser has not been able to make a successful connection to the internet.

Generally, this type of error occurs from the user end, either due to the user having a poor internet connection or has not properly configured DNS. It is also possible that the user has not updated their web browsers or even the server is busy.

Hence, the most common and widely used solution that you must try to fix this issue is by simply restarting your Personal computer or trying on other browsers.

Let us check out what are the more possible reasons for DNS Server not responding on your PC, especially on your Windows device. Since Windows has the major Operating system market share in the world, so let us see what are the reasons for the DNS servers not responding on Windows 10.

Possible Reasons of Dns Server not responding on Windows 10 devices

When a user enters the host’s name in the web browser, it gets translated into IP address by DNS. And the DNS saves all these IP addresses that the user requests in the form of cache. Hence, from this, there can be only two possibilities that cause this error to happen in Windows 10 devices. They are:

  1. Exhausted Cache Memory: You have already read that all the IP addresses that user request is stored in DNS as cache memory, so that whenever the user like to visit the website again, it has not go through the same process again and again.
  2. Malware attacks: Some Malwares or Computer viruses are assigned to steal data from your browser. Similarly, phising is a data stealing technique in which your computer is infected with some malware and Your web data is being stolen from DNS cache or been compromised. Due to this you will be start redirected to some other potential harmful websites.

Now you must be able to understand what are the possible causes that let this error message reflect on your webpage. Let us check out the different methods by which you can fix this issue as soon as possible.

Since only two dominating operating systems are used worldwide, i.e Microsoft and Mac OS, We will talk about solutions for only these two platforms.

Methods to fix Dns Server not Responding error (Windows and macOS)

Now you got the idea about what does the DNS server not responding error means and what are the possible reasons causing it. So it is time for you to know how you can fix this error with the best possible methods available on both the platforms Windows as well as macOS.

1. Check out on different browsers

One of the most common and basic methods that everyone should try first is to check if the error occurs in other browsers too? Sometimes, the DNS server not responding error can be fixed by as simple as changing the browser or updating the current one with its latest version available.

To start with, there are various other popular web browsers are available on the internet such as Mozilla Firefox or Microsoft Edge you can try. If you are a macOS user and your default web browser is a safari you can try on either chrome or firefox instead.

If you won’t find a DNS server issue or an error message, it means there is an issue with your default current web browser. You can either reinstall it or update it with the latest version available.

However, if you still find the error message “DNS server not responding” after switching the browsers, it means, the source of this error is not your browsers.

2. Turn on your Computer in Safe Mode

Sometimes, due to some issues in operating systems, your computer may show a DNS server not responding to error messages on your web browser. Hence, to figure out and resolve this issue you can turn your computer on in safe mode and check if it fixes the issue or not.

In safe mode, all the computer resources and files will get limited that are required to run the operating system, which can be an effective method to resolve this issue.

For Windows 10 or 11 users, you need to,

  1. Click on the Windows button as well as key R simultaneously.
  2. Type “msconfig” in the box provided.
Start Windows 10 on safe mode
Start Windows 10 or 11 on safe mode

3. Select the Boot tab > Safe Boot option and click on the Apply button.

and your computer will boot up in safe mode.

If you are running Windows 7 or older versions, you can restart your computer on safe mode by going to Window button > Restart. While the system is booting up, hold down the F8 key for a while.

For macOS users, the process is almost the same. When your machine is booting up you need to press the shift key unless or until the apple logo appears. Once the logo appears, you can release the key and your Mac machine will start in safe mode.

After that, in safe mode, you can check whether the issue persists while accessing the website again or not. If in safe mode there is no internet or any connectivity issue and if still the DNS server not responding issue occurs, it may be caused due by any third-party application such as antivirus.

3. Check with antivirus and Firewalls

If checking with different browsers as well as accessing the website in safe mode does not help you out to fix the issue, the next method you can try is to disable antivirus and firewalls of your system temporarily.

Antivirus and Firewalls are one of the most important security measures of your system that secure your website from malicious attacks and intrusion. But, sometimes they can also create problems for your system and with your connectivity.
Hence to check whether firewalls or antivirus software are the culprits, you need to disable them temporarily and check if the issue persists or not.

4. Restart your internet Modem or Router

Another easiest troubleshooting method to fix the DNS server not responding issue is by restarting your internet modem or Router. This method helps to clear out your router’s cache memory and that could help you to fix the issue.

To restart your modem, you can simply turn it off by pressing the power button until the led lights stop blinking and wait for 10 seconds. Or it is better to remove the power source from the router/modem and wait for 30 seconds. After waiting for a while, turn on your modem or router back or plug it into the power source again and wait till it can establish the connection.

After doing so, move back to your web browser and check if this method can resolve the “DNS server not responding issue” or not?
