How to Fix: DNS_PROBE_FINISHED_NXDOMAIN in Chrome?

The web browser needs the correct site address to resolve and load a webpage; if it doesn’t, then result in a DNS error. The most effective ways to fix DNS_PROBE_FINISHED_NXDOMAIN in Chrome are re-check the URL, disable the Chrome flags, check the host file, change the DNS server, release and renew your IP address, and reset Winsock. 

I tried accessing a website via Google Chrome, but the connection wasn’t established. Instead, I received the dns_probe_finished_nxdomain error message. Upon further inspecting it, I discovered that the issue was with the DNS and IP address lookup.

The domain Name Server’s role is to translate the website name into a numerical IP Address. For the end-users, typing an IP such as 192.168.0.1 instead of www.example.com would always be a tough job. However, the web still wants the numeric address for each website rather than their plain-text format.

So when you type in a URL, the request goes to the DNS, which then looks up the associated URL’s IP Address in its record and sends it back to the server. The server will then take this request forward; hence, the desired connection is established.

But if there is any issue in the entire process, the browser will throw up a DNS-related error, one among which is the NXDOMAIN.

A short form for the non-existent domain appears when the DNS cannot find the associated IP Address corresponding to a particular URL in its record book.

So how could a user fix this underlying issue? Well, this is where this guide shall help you out.

Re-check the URL

If you have entered an incorrect URL, then the DNS wouldn’t be able to get hold of its associated IP Address and would display the error. Therefore, reverify that there’s no typing error.

Release and Renew Your IP Address

Issues with the IP Address could also be the reason behind this DNS error. In this regard, you could release your current IP Address, delete all the cache left behind, and then ask for a new IP Address from DHCP to be assigned to your system.

Here are the steps to Release and Renew the IP Address in Windows OS:

  1. Head over to the Start menu,
  2. Search for cmd, and launch it as an Administrator.
    Run Command Prompt as Administrator
  3. Execute the following three commands, one after the other:
    ipconfig/release
    ipconfig/flushdns
    ipconfig/renew

The first command will release the currently assigned IP; the second one will flush the DNS Cache of that address; the third and final command will replace it with a new IP Address.

Once all three commands are executed, restart your PC and see if it gives any favorable results.

Reset Winsock

Windows Socket is a term given to the data stored on your PC responsible for establishing a successful connection between an app/software and the network.

Sometimes, you might have encountered issues when the WiFi is running well, but a particular device is still unable to access the internet. In such cases, the issue is usually with the Winsock, and the best bet is to reset it.

Here are the steps to Reset Windows Socket or Winsock:

  1. Launch Command Prompt as an Administrator.
  2. Type in the below command in the prompt window:
    netsh winsock reset

    netsh winsock reset command in Windows OS

  3. Hit on Enter keyboard button.

There isn’t any major issue with resetting Winsock but make sure you don’t make it a habit of fixing network issues via this tweak. This is because if this need arises regularly, then there might be some other (major) issues with your PC’s Network Adapter that needs troubleshooting.

Change DNS Servers

Your Internet Service Providers assign the DNS servers that you are currently using. However, they aren’t fixed, and you could also redirect them to other servers.

In this regard, Google DNS and Cloudflare DNS are usually the two preferred choices, out of which we would be going ahead with the former one.

Here are the steps to Change DNS Server Address in Windows:

  1. Launch the Control Panel from the Start menu.
  2. Open the Network and Sharing Center.
  3. Click on Change Adapter Settings from the left menu bar.
    Change Adapter Settings in Windows OS
  4. Right-click on the network to which you are currently connected, and select Properties.
    Network Connections WiFi or Internet Modem Properties
  5. Scroll and select Internet Protocol Version 4 (TPC/IPv4), and click the Properties button.
    Internet Connection WiFi IPv4 Properties.
  6. Select Use the following DNS server addresses radio button.
  7. Enter follow Google DNS addresses:
    Preferred DNS server: 8.8.8.8
    Alternative DNS Server: 8.8.4.4
    Use Google DNS settings in Internet Properties Option
  8. Hit on OK to save the changes.

Now try accessing the website and check whether the DNS_PROBE_FINISHED_NXDOMAIN issue has been rectified.

If you instead prefer to go for Cloudflare DNS, then replace the Preferred and Alternate DNS with 1.1.1.1 and 1.0.0.1, respectively.

Check the Host File

A Host file is used to map a connection between the web address and its IP Address. However, it could also block a specific website from being accessed.

This is usually done by assigning it a loopback IP address (such as 127.0.0.1). So you should check the host file and verify that the concerned site is not blacked out.

Here are steps to check the Host File in Windows:

  1. Launch the File Explorer, and head over to the below location:
    C:\Windows\System32\drivers\etc
  2. You should find a host file and open it using the Notepad app.
    Windows Network Hosts File
  3. Scroll to the end, and check if there is a mention of your site and the localhost address – 127.0.0.1.
    Delete the Line to Unblock website in Hosts file
  4. Delete any blocking entries, and save the file with Ctrl + S keypress.

Now try accessing the site; the issue should have been fixed after unblocking the URL.

Disable Chrome Flags

Chrome Flags are experimental and are used to test beta features before their final release. These flags encompass a broad domain; some are directed exclusively toward the network.

So if you have enabled any such network-related flag, try reverting them to their original state from the chrome://flags page. Most probably the Default status.

Bottom Line: Fix the NXDOMAIN error in Chrome

So this was all from this guide on how to fix the error. This site can’t be reached due to DNS_PROBE_FINISHED_NXDOMAIN in Chrome. We have shared a total of six different fixes – two basic ones and four along the lines of slightly advanced fixes.

In my case, flushing the DNS did the trick. There had been a lot of temporary data related to my current IP address accrued over time. So deleting them and then letting the DHCP assign a new IP address worked out.
