In some cases, you may receive a message that webpage is not available when trying to open any website. In addition, near this message you can see the Error DNS_PROBE_FINISHED_NXDOMAIN. Usually, this error appears in the Google Chrome. However, you may encounter this error in other browsers like Opera, Mozilla Firefox etc. It’s also important to mention that this error can appear in Windows 10 and any other Windows versions.

This error looks like this:

The error of this kind can occur when:

1. There is no internet connection;
2. The firewall blocks the browser used to access the Internet;
3. You are using an invalid DNS server.

When such error occurs, it is recommended to perform a few simple actions which can help in most of the cases:

• Be sure to reboot your computer and the router or modem (if you have one). The router should be turned off for a few minutes;
• Check if the internet connection is working properly, look at the status of the connection. If you have a connection through a router – check whether there is an access to sites from other devices;
• If there is no access to only one specific site, and the rest are opening without problems, then it is possible that the problem is on the site’s side;
• Try to open websites using a different browser;
• If you’ve changed some settings on your computer before getting the dns_probe_finished_nxdomain error, or installed some programs (for example, an antivirus etc.), then undo the changes – this should help;
• Try to temporary disable the antivirus and built-in Windows Firewall.

Reset Network Adapter Settings

First of all, try to reset network adapter settings and purge DNS cache. To do this open elevated Command prompt and run the following commands:

ipconfig /release

ipconfig /flushdns

ipconfig /renew

netsh winsock reset

Reboot your computer and check whether the DNS_PROBE_FINISHED_NXDOMAIN error has been fixed. If problem still persists, go to the next step.

Disable Firewall

Try to temporarily disable the Windows Firewall.

You can disable Windows Firewall from Control Panel: Control Panel -> System and Security -> Windows Firewall -> Turn Windows Firewall on or off.

You can also disable it using Command prompt:

NetSh Advfirewall set allprofiles state off

Also do not forget about the antivirus. Often it also has a built-in firewall that can block the internet access to the browser.

Try to open the site again. If the error is resolved, create a rule in the firewall that allows outbound connections for your browser (Control Panel -> System and Security -> Windows Firewall -> Allow an app or feature through Windows Firewall). Tick the checkboxes for private and public networks for your browser and click OK.

To turn on the Windows Firewall, run the command:

NetSh Advfirewall set allrprofiles state on

DNS Settings

Check the DNS settings on your computer. Open Control Panel -> Network and Internet -> Network Connections, right click on your network connection and select Properties. Select Internet Protocol Version 4 (TCP/IPv4) and press button Properties.

Select the option Use the following DNS server address and specify the following IP addresses of public Google DNS servers:

• 8.8.8
• 8.4.4

DNS Client service

Check if the service which is responsible for converting DNS addresses is turned off. Press Win + R and enter the services.msc command.

Check the status of the DNS Client service. It must be in the Running state and have the startup type Automatic.

Try to open the problematic website now, the DNS_PROBE_FINISHED_NXDOMAIN error should disappear.
