This guide will help you troubleshoot the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. This error usually occurs when you cannot connect to the DNS server.

“This webpage is not available” is a common error message that most of us have seen many times. The reasons for such an error may vary, but in this guide we are going to show you a few quick fixes that may help you solve it. Usually, the “This webpage is not available” error message indicates some issues with the DNS configuration. In Chrome, it comes with a grey massage stating something like “DNS_PROBE_FINISHED_BAD_CONFIG” or “DNS_PROBE_FINISHED_NXDOMAIN”. What this message means is that the DNS (Domain Name System) is having trouble finding the Webpage you requested.


Generally, DNS is responsible for the translation of the domain name to the numerical IP addresses and in most cases, the settings of the IP and DNS addresses are automatically assigned when your device is connected to the router. However, if these DNS settings are corrupt or wrong, your browser won’t be able to access the Internet. In this case, you will receive the “DNS_PROBE_FINISHED_BAD_CONFIG” message whenever you try to visit a website. Depending on the browser you are using, it may state something like this:

  • For Google Chrome: “This webpage is not available” DNS_PROBE_FINISHED_BAD_CONFIG” or similar.
  • In Mozilla Firefox: “Server not found. Firefox can’t find the server at www.this-and-this-site.com.”
  • In Internet Explorer: “This page can’t be displayed”

In this guide we will provide you with detailed instructions on how to solve the “dns_probe_finished_bad_config” & “dns_probe_finished_nxdomain” error message in the Google Chrome browser. Below you will find five solutions, which we hope will work for you.


The Guide

Fix 1. Run a virus scan on your device

Before you continue with your attempts to troubleshoot your Chrome connection problems, it is best that you first scan your device for viruses and malware. Such harmful programs may cause issues with your Network and Internet connection abilities and detecting and removing them may be the solution you need. This is especially true if this error only occurs on some pages.

Fix 2. Restart your Router

Sometimes, the reason for your inability to load a webpage may be with your router. A simple restart often helps to renew the Internet connection and here is how you can do that:

  • First, unplug the power cord from your router and wait at least some 30 seconds.
  • Then, plug the power cord back in again and restart your device.
  • This should solve the problem and you can try to connect to the Internet with your browser.

Fix 3. Reset TCP/IP Protocol

  • For this fix, you will need to open the elevated command prompt window.
    If you are using Windows 7 & Vista you need to go to:
    Start > All Programs > Accessories
    • Right-click on “Command prompt” and choose to “Run as administrator”.
    If you are using Windows 10, 8 & 8.1 versions:
    • Simply give the Windows start button a right-click of the mouse and select Command Prompt (Admin) as shown in the picture below.
  • As soon as the the command prompt window appears, you will need to type the following command “netsh int ip reset” and hit the Enter key on your keyboard.
  • Once done, close the command prompt and restart your computer for the changes to take effect.

Fix 4. Refresh IP Address and Reset DNS Address settings

  • Open the elevated command prompt the same way as shown in Fix 3.
  • This time, in the window that opens you will need to type these three commands by strictly following their order and pressing Enter after typing each of them.
    1. ipconfig /release
    2. ipconfig /flushdns
    3. ipconfig /renew
  • Next, close the command prompt and restart your computer for the changes to take effect.

Fix 5: Change the DNS Settings

Normally your ISP provides the default DNS server which your PC can use. If that server is experiencing problems you can try changing it to one of the free Google DNS servers, which work just as fine. We’ve provided the instructions below.

  •  For this fix, you will need to go to Control Panel > Network and Sharing Center.
  •  Next, click the “Adapter Settings” on the left.
  •  Then, double click to open the active Network Connection (for example, the “Local Area Connection”).
  •  Once there, you will need to first click the ‘Internet Protocol Version 4 (TCP/IPv4)‘ and after this click “Properties”.
  • After this, choose “Use the following DNS server addresses” and type the Google DNS Server addresses as shown below:
  •  Click OK to close the network properties.
  •  Finally, restart your computer for the changes to take effect.
