Find out how to fix the DNS_PROBE_FINISHED_NXDOMAIN “This site is unreachable” error message in Google Chrome. You can try the various working fixes mentioned.
Recently I was trying to access a website through Google Chrome, but unfortunately the connection was not established. On the contrary, I was greeted by the dns_probe_finished_nxdomain Error message. Upon further inspection, I discovered that the problem was related to the DNS lookup and IP address.
The role of the domain name server is to translate the name of the website into a numeric IP address. For end users, enter an IP address such as 192.168.0.1 instead of www.example.com would still be hard work. However, the web still wants each website’s digital address, rather than their plain text format.
So when you type in a URL, the request is sent to DNS which then finds the IP address of the associated URL in its record and sends it back to the server. The server will then transmit this request and the desired connection is established.
But if there is any problem in the whole process, the browser will generate DNS related error, one of which is the NXDOMAIN.

Check the host file
A host file is used to map a connection between the web address and its IP address. However, it can also be used to prevent access to a specific website.
This is usually done by assigning it a loopback IP address (such as 127.0.0.1). You must therefore check the host file and verify that the affected site is not hidden.
Here are the steps to verify the host file on Windows:
- Launch the File Explorer, and head to the location below:
- You should find a host file, open it using the Notepad app.
- Scroll down to the end and check if there is a mention of your site with the address of the local host – 127.0.0.1.
