One such error occurs to which most users encounter is ERR_NAME_NOT_RESOLVED.

This guide has covered the causes and fixes to resolve the error.


The working of the internet is dependent on Domain Name System or DNS. DNS finds the IP address for a mentioned website domain name. It enables web browsing data to work swiftly, even when millions of websites are on the internet. Occasionally, your system cannot detect the IP address, giving an ERR_NAME_NOT_RESOLVED DNS ( Domain Name System) problem. 

Here is a comprehensive guide about the ERR_NAME_NOT_RESOLVED, the reasons behind it, and the workable fixes for the ERR_NAME_NOT_RESOLVED.  

Significant variations of the error:

  • This error occurs in the following primary forms
  • The site data can’t be reached
  • The webpage is not available


This error occurs when your browser or computer cannot find the particular IP address hosting the domain name the user is visiting.

To understand this error more deeply, one needs to know preferred DNS server addresses and their working. When a user uses a website address through a system such as, the system passes a DNS ( Domain Name System) request to have access to the IP address of the web server hosting the website.

This search process can be swift if the internet or browser service provider has already saved the IP address in its cached files. In other cases, if the matching address is not found in the DNS entries, the domain name resolution process begins to get the IP address.

In some cases, the error happens when the access to the website may have changed the IP address, and the system still directs the user to the old cached address. The browser will be directed to the outdated address stored in the cache; 

Hence the error message is triggered with the message that the domain name cannot be resolved. 

Other possible causes which can make the DNS fail to access the website or domain name include the following:

  • Incorrect network configuration
  • The improper browser or internet settings
  • Wrong DNSSEC application

9. Try repairing the Hosts File

The system always has a host file with IP addresses and domain names. When a website opens system looks for the hosts’ file to look for a matching IP address and domain name. The operating system will only ask for a DNS request if no matches are found.

Adding the website when the IP address of the website to the hosts’ file can resolve to browse data problems related to preferred DNS server addresses. This method is also applicable to finding out the error source. If the site data opens after mentioning the domain name and the IP address in the host file, then the problem was mainly arising from your side.

3. Check if a Different Internet Connection Works

Internet connection is sometimes the source of error. So you can check the internet settings and related functions for this. There are mainly two tests to check internet settings and to confirm this.

The router will take some time to become fully functional again. When they become light turns green, your computer will get connected to the network. Now test it again.
