Google Chrome is the leading web browser owing to its efficiency, security, and other features. Its popularity notwithstanding, users do report having to face occasional problems while using it. A recurring error encountered by Chrome users is “Server DNS address could not be found.”
It occurs when the browser is unable to access a website. Chrome users on various Windows versions face it, be it Windows 8 or 10. This article is about the nature of the “Server DNS address could not be found” error, and the ways to fix it.
What Is Server DNS Address Could Not Be Found Error?
Every website has an Internet Protocol (IP) address in numerals and a domain name by which people know it. When a user enters the domain name of a website in a browser, the browser contacts a DNS server. The Domain Name System (DNS) server, in turn, matches the domain name of the website with its IP address. In this way, the browser can fetch the website for the user.
However, the DNS server may often fail to locate the IP address for a domain name. The browser is then unable to access the website, and the error message appears on the screen. This error can occur if for some reason the server is down, or if the local cache is sending an obsolete IP address. Whatever be the cause, the user is unable to access the intended website due to this error.
Fortunately, there are certain techniques to resolve this problem. Check the methods described below, and try them to fix the “Server DNS address could not be found” error.
Solution 1: Update the DNS
An effective way to fix such errors is to update the DNS by shifting to the Google Public DNS servers. Google’s public DNS service is free and open to all users. Following are the steps to change DNS settings to use Google servers:

Then click OK.
Step 9: Reboot your device to check if the Server DNS Address Could Not Be Found error is solved.
Solution 2: Look Up IP and Add to Hosts File
If the server is trying to access an old IP of a domain, the error occurs. However, you can easily locate the new or correct IP of the domain and then add it to the Hosts file. It may fix the error. Follow the steps below to try this method:
Step 1: Open the whatsmydns.net website.
Step 2: In the search box, type and enter the domain name
