Imagine trying to open your browser only to see a message saying that the current site you’re trying to assess cannot be reached followed by a “dns_probe_finished_nxdomain” error. It’s a situation that can even turn the timidest of us into a path of fury and rage. There’s a vast multitude of things that could have potentially gone wrong, but one of the most common ones is faulty DNS servers.
So, what exactly is “dns_probe_finished_nxdomain”, and why are you seeing it? Are there some quick fixes to resolve the issue?

Firstly, what is DNS?
DNS or Domain Name Server is akin to a phonebook. It lets users connect to the right website using specific domains rather than IP addresses. The basic purpose of a DNS is to translate the name of the host (www.randomdomain.com, for instance) into a lot more advanced IP address (18.104.22.168) that your computer can easily process. When you type in a query into the search bar, DNS gets to work and goes through its extensive collection of nameservers to determine the right fit.
The process of DNS looking for the appropriate file among the thousands in the nameserver is a laborious process, but in real-time only takes a couple of seconds at best.
So, when you type in something in the search bar of your browser, it makes its way through the Internet only to reach another DNS recursive resolver. This information travels to the DNS root nameserver and then to the Top Level Domain (i.e .in or .org).
Now, the TLD server shoots back a response in the form of the IP address of the domain’s nameserver. Finally, the recursive resolver comes into play, and the IP address that was initially requested before starts to appear.
So, what is the dns_probe_finished_nxdomain error?
Reiterating that the process of resolution and DNS lookup is a highly complex process with a large number of moving parts. So, a lapse in any of these parts can result in an error that manifests as dns_probe_finished_nxdomain. In fact, the nxdomain in “dns_probe_finished_nxdomain” stands for a non-existent domain.
You can see a warming message in different ways depending on the browser you often use. In the case of Google Chrome, the error shows up as “dns_probe_finished_nxdomain”, along with a message saying that the server IP address could not be found or this site can’t be reached.
If you’re a Mozilla Firefox user, then you might be seeing something along the lines of ‘Hmm, we’re having trouble finding that site’. Microsoft Edge more or less follows the same pattern with a notification indicating Hmmm…can’t reach the page. Safari, the default browsing app on all Apple devices, simply displays Safari can’t find the server.
Before we go on to the actual fixes of the “dns_probe_finished_nxdomain” problem, it’s pertinent to identify where the issue lies. An easy way to do this is by checking if you’re seeing the “dns_probe_finished_nxdomain” error only on a single website or across multiple web pages.
In case the error is localized to a single site, then it could be an error on their side, and you have nothing to worry about. Just wait for some time and try accessing the website again. But, on the other hand, if you’re seeing the “dns_probe_finished_nxdomain” message across different pages, then it’s time to intervene and test out the methods listed below.
How to fix the “dns_probe_finished_nxdomain” error?
While there are multiple ways to resolve the issue under consideration, here’s a list of methods that most IT professionals would stand by to fix the “dns_probe_finished_nxdomain error”. We’ll discuss each one of them in the further sections.
- Releasing and renewing IP addresses
- Restarting DNS Client Servies
- Changing to a different DNS server
- Resetting Chrome Flags
- Shutting down VPN’s and other antiviruses temporarily
- Checking your Local Hosts files again
- Restarting your computer/ laptop
1) Releasing and renewing IP addresses
In “Dns_probe_finished_nxdomain” error there isn’t exactly an error from your side, so it does make sense to take a second look at the IP address on your device. Releasing and renewing your IP address isn’t as complicated as it sounds. Follow these series of steps to successfully accomplish the task.
On devices running on Windows OS
- Step 1: Navigate to the Command Prompt by pressing on the Windows and R key simultaneously. Once you’ve found the Command Prompt tool, type in “cmd” on press Enter.
- Step 2: Now, enter in ipconfig /release and press Enter. This should ideally release your existing present IP address.
- Step 3: Next up, type ipconfig /flushdns and tap on Enter. This ensures flushing your DNS cache. You should now be able to see a message “Successfully flushed the DNS resolver cache”, in case the process was successful.
- Step 4: After this, you’ll need to type in ipconfig /renew and press Enter. This renews your IP address.
- Step 5: If you want to reset your IP settings, then type in the following commands netsh int set dns and netsh winsock reset.
In case Step 5 seems hard to follow, you can always manually disable your network connections and re-enable them again. To perform this, go to Control Panel on your Windows computer from the Start menu. Now, click on Network and Internet Settings and navigate all the way down to Network and Sharing Center.
You’ll see an option called Change Adapter Settings in the left-hand column, click on it. This should open up a new portal with a whole list of active network connections. Click on Local Area Connection or Wireless Connections and choose to Disable. You can reactivate them later in the same manner.
- Step 1: Find System Preferences by clicking on the Apple logo at the top right corner of your laptop/ computer.
- Step 2: Now, click on the Network icon and go to Advanced Settings.
- Step 3: Navigate to the TCP/IP tab and choose to “renew DHCP lease button”. This ensures that your IP addresses’ renewel.
- Step 4: You can also flush your DNS cache by going to the Utilities tab and clicking on Terminal.
- Step 5: Type in the command dscacheutil -flushcache and press Enter. Unlike in a Windows device, you might not get the confirmatory message in case the DNS cache has been emptied successfully.
2) Restarting DNS Client Service
This method is exclusively for Windows devices. You can try restarting the DNS client services, which supposedly clears up redundant caches and obsolete DNS domain names. Follow the steps to successfully restart your DNS client services.
- Step 1: Open Command Prompt by pressing the Windows key and R key simultaneously.
- Step 2: Once Command Prompt opens, enter in “services.msc” and press Enter.
- Step 3: Go down to the bottom where you’ll see “DNS Client”. Right-click on it and choose “Restart”.
If the Restart button is greyed out and you’re unable to click on it, then consider this alternate method.
Step 1: Go to Command Center by pressing on the Windows key and the R key simultaneously.
Step 2: Now, enter in “cmd” and press Enter.
Step 3: Enter in these series of commands: net stop dnscache ; net start dnscache
You could run into an error in some versions of the Windows OS. You might be seeing a message saying “The requested pause, continue, or stop is not valid for this service”. This is an indication of the fact that you’re better off picking an alternative method altogether.
3) Changing DNS servers
You can always try changing your existing DNS servers from the default ones to public DNS servers like Google or Cloudflare. DNS servers typically make use of the IP addresses assigned by the ISP, so switching to a public server could effectively correct the persisting “dns_probe_finished_nxdomain” error.
If Google servers are your pick, then the 22.214.171.124 and 126.96.36.199 are easily your best bet. Word in the community is: they’re more dependable in the longer run. But, Cloudfare’s newest offering, the 188.8.131.52 is a worthy alternative as well. It’s popular to achieve faster speeds consistently.
But, on the off chance that you’re already using a free server and still seem to be encountering the same issues, going back to your default server can correct the issue. Google and Cloudfare, despite their claims, can run into roadblocks sometimes.
Here’s how you change your existing DNS addresses:
On Windows devices
- Step 1: Open the Command Prompt by pressing on the Windows key and R key simultaneously.
- Step 2: Type in Control Panel and press Enter.
- Step 3: Now, go to Network and Internet Settings and click on Network and Sharing Center.
- Step 4: You should be able to see an option to Change Adapter Settings, click on it, and find your currently active network connection.
- Step 5: Pick either the Local Area Connection or Wireless Network and go to Properties.
- Step 6: Select Internet Protocol Version 4 or 6 depending on your preference and click on “Use the following DNS server addresses”.
- Step 7: Change the addresses to the following: 184.108.40.206 and 220.127.116.11 (for IPv4), 2606:4700::1111 and 2606:4700::4700:1001 (for IPv6).
- Step 8: Press on OK once you’re done and restart your browser to complete the process.
- Step 1: Navigate to System Preferences from the drop-down menu that appears when you click on the Apple logo at the left-hand upper corner of the screen.
- Step 2: Click on the Network icon and then on Advanced.
- Step 3: Now, find the DNS tab and click on it.
- Step 4: You’ll now need to enter in the new server addresses powered by either Google or Cloudflare. For Cloudflare servers, use the following DNS server addresses as mentioned above in the previous section.
4) Resetting Chrome Flags
If your default browser is Chrome, then pay close attention to this method. In some exceptional cases, the settings on your Chrome account may experience altering accidentally, consequently going a little haywire. To go back to the default settings, type in chrome://flags into the browser. In the portal that opens, pick on Reset all to default. Remember to restart Chrome once you’re done resetting the Flags or other similar experimental features.
You can also try cleaning the browser. This method stays the same across all devices. Follow the steps given below to clean Google Chrome.

To shut down VPN, type in Network Connections in the search bar and click on View Network Connections. You’ll be seeing a VPN icon, so click on that and choose to Disable.
6) Checking your Local Hosts files again
The Local Hosts file on your computer houses all the manual DNS entries, which are linked to unique IP addresses. This treasure trove of data may sometimes get altered or, in worse cases, get corrupted.
So, it might be worthwhile to cross-check if the domain of your interest is in this collection or not. Usually, these local files are accessed during a preview of the DNS settings before switching domains from one host.
Here’s how to check your Local Hosts files across different platforms :
On Windows devices
- Step 1: Go to the Start Menu and look out for the text editor. Right-click on it and pick the option that says Run as Administrator. These text editors could be anything from Notepad to Atom or even Sublime.
- Step 2: Now, in the text editor that you’ve chosen, click on File and open this specific location- C: \Windows\System32\drivers\etc.
