Have you accessed a domain, and you have seen the message in the browser? In this post we will talk about it.

Any user may encounter this error message, followed by “Cannot access this site”. It is strictly related to the DNS servers; the website cannot be found.

When you enter, for example, in your browser, it translates to an IP address, In order to find the exact IP address to be resolved, a series of queries are first made to several name servers, in order to serve the content. If for some reason there are conflicts in the DNS servers, the message "DNS_PROBE_FINISHED_NXDOMAIN" will be displayed.

Does the DNS_PROBE_FINISHED_NXDOMAIN error appear the same in all browsers?

Each browser has its own way of displaying the DNS_PROBE_FINISHED_NXDOMAIN error. Here is a list of the messages of the most used browsers:

  • Google Chrome is the browser that most clearly indicates the error message, displaying DNS_PROBE_FINISHED_NXDOMAIN, along with "Cannot access this website, check for a script error at".

  • Safari, Apple's browser, shows us the error stating "cannot find the server. Safari cannot open the page because it cannot find the server '".

  • Mozilla Firefox returns the message "Ugh. We're having trouble finding that site. We can't connect to the server at".

  • Microsoft Edge warns of connection failure with "Wow... unable to access this page. Check if there is a typo".

Possible causes

This error can be for several reasons, and it's always the same: For some reason, your web browser can't get the IP address of the server that contains that web page. Why can't they get the IP address? Here is a list of the.

  • The domain has been typed incorrectly in the browser.

  • The domain is not registered or has expired.

  • Use of VPN or Antivirus that cause interference.

Basic revisions

Check the DNS

  • Check the DNS servers of your domain to make sure that they are properly configured.

Clear browser cache and cookies

One solution may be to clear the cache and cookies (these are small data files), as they can become obsolete or corrupt. Here is how to do it in the most common browsers.

Google Chrome:

  • Go to Settings > Privacy & Security > Clear Browsing Data. Select “Cookies and other site data” and “Cached files and images”, the time range to delete and click “Clear data".


  • Click Safari > Settings > Privacy > Manage website data. You will need to select the time range you want > Clear History.

Mozilla Firefox:

  • Go to Settings > Privacy & Security > Cookies and site data > Clear data.... . Then check both boxes and click “Clear” to finish.

Check your Internet connection.

  • Try a different website. Can you access other sites, such as or ? If not, the reason is probably your Internet connection, not the website you are trying to access.

  • Try accessing from another device, or from another network. It could be your Smartphone's mobile data, or the wifi network you are using.

  • Contact your Internet Service Provider (ISP) if all else fails to get help to fix it.

Advanced revisions

Reset Google Chrome flags

  • In the Google Chrome address bar, type chrome://flags and press Reset all. At the bottom of the browser, you will need to press the “Relaunch” button to apply the changes. This action will restart Google Chrome.

Clear your DNS cache

Just like browsers, operating systems also store cache. In clearing DNS cache, you can make your connection go faster, and connectivity issues. This can be done on different operating systems.


  • Press the Windows + R keys at the same time.
  • In the window, type cmd to open the Windows console.
  • Type the command ipconfig /flushdns to clear your computer's DNS cache, and press the Enter key.


  • Press the Ctrl + Alt + T keys at the same time to open the Linux terminal.
  • Type the command sudo /etc/init.d/nscd restart and press the Enter key to clear the DNS cache. This process will prompt you for your user password.

Your Linux distribution may have another service for DNS resolution. In case you don't have it, we recommend to check which is your service in charge of DNS resolution.


  • Press the F4 key > Terminal, or open the LaunchPad in the Doch and type > Terminal.
  • Type the command sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder and press the Enter key to clear the cache. This process will prompt you for your user's password.

Restart DNS client in Windows

  • Your Windows DNS service may have temporary failures. To access it, press the Windows key on your keyboard, type Services and open the application.
  • In the list, go to the service whose name is “DNS Client”. Right-click on the service > Restart.
