What is the DNS server?

The DNS (Domain Name System) server is a system that helps the user to connect with websites on the internet and it is used whenever a person connects to a website for the first time.

How? He requests data by contacting the server where the files on this site are hosted. This server, in turn, is identified by a numeric address, which we call IP.

This IP is made up of a series of confused digits that are very difficult to remember, but the DNS server assigns an easier name for the site, for example, rockcontent.com.

What does DNS server not responding mean?

We often find websites with loading problems on the internet even when our internet is working very well, isn’t it?

It appears in Chrome, the most used browser, as follows: DNS_PROBE_FINISHED_NXDOMAIN.

How to fix the problem of DNS not responding?

As we said at the beginning, the DNS problem can be daunting at first, but it is quite simple to fix!

Check out the main resolutions now:

Clean your cache

It is in the DNS cache that all the IPs of sites visited by you are stored, and cleaning it can be a good way to solve the problem, since, if an IP address that is out of date, can cause the error DNS_PROBE_FINISHED_NXDOMAIN.

To do this correctly, just run the Command Prompt as a Windows admin, type “ipconfig / flushdns” and hit Enter.

Change the DNS server

Did you try to clean your cache but it didn’t work? It might be a good idea to change the DNS server.

To escape this error, many people end up choosing to use Google DNS, because, in addition to a better connection, it offers more stability and speed.

You can make this change by following the step by step below:

  1. Access your Control Panel and open the “net and sharing central”.
  2. On the left side, select the option “Change adapter settings”.
  3. With the right button of your mouse, click on the connection used and select “properties”.
  4. Now, select “IP Protocol Version 4 (TCP / IPv4)” and then click “properties”.
  5. In this part, you will come across two blank fields. It is in these fields that you can define which servers are preferred and the alternative of your PC. The addresses used by Google are 8.8.8.8 and 8.8.4.4, and openDNS 208.67.222.220 and 208.67.220.222.
  6. Select OK and exit.

Disable your antivirus and VPN

Although very efficient, the combination of antivirus and VPN can interfere with the access of some sites. So, if you are experiencing a DNS error, try to disable them first.

To disable VPN, follow the step by step:

  1. Go to your Control Panel;
  2. Select “Network and Internet ”and then“ Network Connections ”.
  3. Soon, you will come across the list of all the connections you have.
  4. Choose which VPN you want to disable.
  5. Select “Change the settings for this connection”.
  6. After that, select the “Network” tab at the top of the window, and then click the Uninstall button.
  7. Now just restart your computer.

Reset Chrome Flags

Some features of Google Chrome may have errors when running, as some are in the testing phase and are available to users around the world. This can also cause errors on the DNS server.

Try resetting your browser settings by typing “chrome: // flags /” in the navigation bar. This can cause the error to disappear and you can return to your normal navigation.

Adjust the IP Address from the Command Prompt

This action is almost a cache cleaning, however, a little deeper. To make this adjustment, you need to access the Command Prompt as admin and enter the following codes:

ipconfig / release

ipconfig / all

ipconfig /

ipconfig /

netsh int ip set

netsh winsock

Remember to enter one command at a time and press Enter after each one.

The DNS server error, or DNS_PROBE_FINISHED_NXDOMAIN error, is very common and also simple to resolve.

Although it looks complicated at first or gives you an initial headache, just a little research is needed to find the best resolution for it.

Now that you know what the resolutions of this problem are, how about staying on top of the main errors that can happen in WordPress and how to solve them? So you can become a real expert on the subject and be more prepared if you encounter one of these problems along the way.
