Resolving DNS_PROBE_FINISHED_NXDOMAIN Google Chrome Error

The server at the website URL can't be found because the DNS lookup failed. DNS is the network
service that translates a website's name to its
Internet address. This error is most often caused
by having no connection to the Internet or a
misconfigured network. It can also be caused by
an unresponsive DNS server or a firewall preventing
Google Chrome from accessing the network.

Error code: DNS_PROBE_FINISHED_NXDOMAIN

If you are getting DNS_PROBE_FINISHED_NXDOMAIN error message when you are trying to access a website on Google's Chrome Browser, then it's due to DNS lookup failure

Its an acronym for Domain Name Server. They are like a phonebook for the Internet. These servers maintain a directory of domain names and it corresponding IP address.

As a Simple Example its something like this :

www.google.com => 173.194.117.84
www.yahoo.com => 106.10.139.246
www.bing.com => 204.79.197.200

www.google.com it the domain name whereas 173.194.117.84 is its IP address. We have domain names because it's easy for us humans to remember names instead of IP addresses. We need them because the machines access websites using domain names.

When you type in a website URL in your browser, the first step that the browser does it "Resolving the URL DNS" so it queries the DNS server and tried to find the IP address, but it seems that the DNS server is not able to fetch the response or is not accessible at all because you have either misconfigured DNS settings in your Internet/Network settings or the firewall is preventing browser to access the network.

1. Check if the issue persists on all websites you're trying to reach, if yes then just check your Internet settings again.
2. Try contacting your ISP (Internet Service Provider) and ask for the DNS settings.
3. If you are not able to access a particular website through any of the web browsers then it may be because the website may be blocked by the government or ISP in your country.

For Windows Operating system users (Windows XP,7,8,10),

1. Press Ctrl + R to open RUN prompt.
2. type : services.msc
3. Look for DNS Client
4. Right Click on DNS Client and click : Restart
5. Restart Chrome and it should work.
