How to Fix “DNS Server Not Responding” Error

These days, most of the things you want or want to work with are available on the internet, which is why most people look for either as their need. You can access and identify a specific website due to its domain name. 

A domain name is the website’s official name, which must be registered for someone to own it. And when it comes to the domain name, another term, Domain name server or DNS, comes along. 

A domain name server is something that translates domain names or hostnames into Internet Protocol addresses. As you have used the internet for many things, you must also have encountered the error which says “DNS Server Not Responding“, which is pretty standard and easy to get rid of. 

So let us now get onto the process of how to fix the “DNS Server Not Responding“ error. 

What Does “DNS Server Not Responding“ Mean?

As we told you, in brief, the domain name server is the directory responsible for translating the domain names or the hostnames to internet protocol addresses. So to fix the “DNS Server Not Responding“ error, it would be better if you knew what it is. 

 “DNS Server Not Responding“ means that the connection which had to be made by the domain name server with the browser has failed, or the server you are trying to reach does not exist or is unavailable. 

This “DNS Server Not Responding“ error is easy to fix as this problem usually lies on the user level, so you do not have to dig deeper to resolve this. And in this article, we will show you eleven ways to fix the “DNS Server Not Responding“ error.

  • Select Network and Internet.
  • In Network and Internet, select Network and Sharing Center.

  3. Follow the instructions on the screen. 
  4. Once the scanning is complete, select Info in the Summary to know more about each entry. 

2. Connect With a Different Device

The next thing you can do is connect the home network to a different device and try to access the website. This will tell you if your home network or device has a problem. 

If you can now access the website with a different device and the same home network, the problem lies with your old appliance, which you used to access at first. 

If you are still unable to access the website, there is a probability something is wrong with the home network or the router. To test this, you may try to connect with mobile data and try to access the website. And if this trial fails, then the problem is with the router. 

3. Switch to Another Web Browser

Another way you can get rid of this “DNS Server Not Responding“ error is by switching to another browser. For example, you currently use Chrome to move to Firefox or another browser. 

If this method works and you can access the website, you may update your browser to the latest version. And if you still see the error, your browser might not be the issue. 

How do I move to another Browser?

  2. Once you are done with that, click on the Library icon and select Bookmarks; now, click on Show all Bookmarks
  3. Click on “Import Data from Another Browser…” 
  4. In the “Import Settings and Data” box, choose “Chrome.” 
  5. While moving, you will be asked which account and what data you want to shift. You will have to click on Continue, and then you are done once the moving is complete. 

4. Restart PC in Safe Mode
