Thi article is quite simple to read. If you still face any issues, you can leave a comment, I will surely help you!

First, let’s learn about what exactly is a DNS server not responding error?

What does DNS server not responding mean?

The Domain Name System (DNS) is the phonebook of the web. We access information online through domain names, like nytimes.com or goal.com. But, web browsers do not follow the same path as humans, they interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load web resources.

Each device linked to the web has a unique IP address that other machines use to locate the device. DNS servers stop the need for humans to memorize IP addresses such as 192.167.1.1 (in IPv4), or more difficult newer alphanumeric IP addresses such as 2400:cb00:2049:1::c629:d7a2 (in IPv6).

In case, the DNS server is unable to complete this name resolution process, you’ll end up getting a DNS server not responding message on your browser screen.

So this error basically means that your browser was unable to establish a connection to the internet.

Normally, this error is caused by issues on the user end, whether that’s with a network or internet connection, misconfigured DNS settings, or using an outdated browser, but in some cases, this error may also appear if the server of the website is temporarily down.

How To Fix DNS Server Not Responding Error

Now, you know what this error means, so let’s learn how to solve it. I request you to pay attention, otherwise, these solutions might not work. Also, If one solution didn’t help, follow the next one. I’m pretty sure that following all the solutions one by one will definitely help you in eliminating this error.

Solution 1: Check Your Router (Restart it)

Most people don’t know that a router is also a computer just like smartphones, tablets, and laptops. Routers like computers have a central processor, memory, and an operating system.

We normally reboot our phones and computers. When those devices are not working well, sp what’s the first thing you should do when your router is not working? That’s right — restart it. You should do the same with your router to give it the chance to reset and start fresh. 

How to restart a router
  • Unplug your router first and your modem second.
  • Wait at least 15 seconds.
  • Plug your modem back in first and your router second.
  • Wait at least two or three minutes before you test whether you are back online.
  • Check your internet.
A suggestion

Never put a router close to a source of heat or hide it behind furniture where fresh air can’t smoothly reach it. Of course, hiding a router behind furniture or placing it close to large metal things is also guaranteed to significantly reduce the router’s range which could bring errors like DNS Server Not Responding.

Solution 2: Use a Different Browser

It might be surprising for some people, but yes, using a different browser may fix the problem. If you think your browser is outdated, then update it quickly and check the site again.

If not, then download a new browser, for example, use Mozilla if your default browser is Chrome.

If using a different browser works, then uninstall your default browser and install it again.

Solution 3: Clear Brower Cache

Web browsers locally store websites on your computer’s hard drive which is called the “cache”.  The cache contains a history of all visited sites as well as images, audio files.  Cookies are also stored in the cache.  They are often stored in the Temporary Internet Files folder.

In many cases, the cached pages will not be current.  When the cache is full, the browser’s performance will slow down. It could also bring errors.

Solution 7: Flush DNS Cache

It’s important to flush a DNS cache for a few reasons.

The first is the cache may contain outdated information. You might experience this as difficulty accessing websites or applications. If the domain name in the cache points to an old or incorrect IP address, the website won’t return the correct information. Even if you clear your browser history, the DNS cache will still have the old information, and the server needs to be flushed to get the updated results.

Another reason to clear the cache is privacy. Although the DNS cache doesn’t contain the same type of information stored in cookies or JavaScript, it does retain a history of which addresses you’ve visited recently, including those you go to on a regular basis. More information stored means less privacy if someone gets access to the cache.
