Solution: ERR_NAME_NOT_RESOLVED: Server could not be found Error

When you open a web browser (like Google Chrome) and launch a website in it, the first thing browser does is to contact a DNS Server. DNS stands for Domain Name Server. This server resolves the name of the website (like apple.com) to an IP address. Sometimes this DNS lookup fails and as a result browser fails to find the server where the requested website is located. In such cases, Google Chrome throws an error that reads like “Error 105 (net::ERR_NAME_NOT_RESOLVED): The server could not be found”. In this article we will tell you how to fix this error. Once the error is removed, you will be able to surf the Internet.

There are a few steps that you should take one by one for solving the ERR_NAME_NOT_RESOLVED error. Here are the steps:

1. Flush DNS for Refreshing its Content

You can flush / refresh your computer’s DNS by issuing simple commands given below:

a) Go to start button and and type cmd in the Run or Search box. Then press Enter key.

b) A black colored command window will open. Here you need to issue three commands.

1)Type ipconfig /flushdns and press enter key

2) Now similarly, type the second command as ipconfig /renew and press enter key

3) As third command, type ipconfig /registerdns and press enter key

c) That’s it. These commands will flush the DNS. Try to open the website in Google Chrome again and see if it works.

2. Try Changing DNS Servers

If flushing DNS does not work, it is possible that your DNS server is having some problem. In such a case, you can use a different DNS. We at TechWelkin prefer to use Google DNS Servers as they are very fast and reliable. Here are the steps to change your DNS server to Google:

The above method of fixing ERR_NAME_NOT_RESOLVED error will set Google Public DNS servers as your preferred servers. This should solve the problem. But if you’re still getting the error, don’t worry! We have more options to try!

As an alternative of Google DNS, you may also try using OpenDNS.

3.Delete Cookies

If the error is still not resolve, you can try deleting cookies from your Google Chrome browser. For this, do as below:

Open Chrome browser.

Copy this address > chrome://settings/clearBrowserData (if you’re unable to copy it, just type it out)

Paste or type the above URL in Chrome and hit enter. The following screen will appear:

ERR_NAME_NOT_RESOLVED 3

Select Cookies and other site and plug-in data option.Click Clear browsing data button to delete cookies.

4.Switch off Router

Just walk up to your Internet connection router and pull the power plug. Keep the router switched off for about a minute. In the mean time you may also power off your computer as well. After about a minute, power on both the computer and the router. Try to open a website in Google Chrome and the problem should be gone by now.

If you’re still facing the problem, it is likely that you’re using an Internet connection in a place like office or cafe. In these places, the computer that serves your Internet connection may be caching the DNS entries. If so is the case, you should contact the administrator of the computer systems.
