What causes the err_name_not_resolved error to happen?

The “ERR_NAME_NOT_RESOLVED” error is a common error message that you may encounter when your browser or computer is unable to identify the IP address of the website you were trying to access. In simpler terms, Your browser doesn’t know where to find the website you’re looking for.

Here are some common reasons for this error:

  • DNS (Domain Name System) Issues: The most common cause of this error is a problem with your DNS configuration. DNS is responsible for translating human-readable domain names (e.g., www.WPOven.com) into IP addresses (e.g., 192.168.1.1) that computers can understand. If there’s an issue with your DNS server or settings, Your browser won’t be able to resolve the domain name to an IP address.
  • Network Connection Issues: If your internet connection is unstable or down, you may encounter this error. Ensure that your internet connection is working correctly.
  • Firewall or Security Software: Sometimes, firewall or security software can block Chrome from accessing the internet or connecting to certain websites. Check your firewall settings and security software to ensure they are not causing the issue.
  • Hosts File: If the website’s domain is listed in your computer’s host file, it can prevent Chrome from resolving the domain name.
  • Router or ISP Issues: In some cases, the issue might be with your router or your Internet Service Provider (ISP). Restarting your router or contacting your ISP for assistance may help resolve the problem.
  • Browser Cache or Cookies: Clearing your browser’s cache and cookies can sometimes resolve DNS-related issues. Try clearing these and then attempt to access the website again.
  • Incorrect URL: Make sure you’ve entered the correct website address in the browser’s address bar. Typos or mistakes in the URL can also lead to this error.
  • Temporary Server Outage: It’s also possible that the website you’re trying to visit is temporarily down or experiencing server issues. In this case, there’s nothing you can do but wait for the website to become accessible again.

How to fix err_name_not_resolved?

Now you have learned that there can be various different reasons that cause the err_name_not_resolved error, there is not a single sure shot method that can fix it. However, if you like to fix it on your own, try these simple troubleshooting methods given below:


1. Try out different Internet Connection

If you tried restarting the router but weren’t able to fix the error, try accessing the website with a different and stable internet connection. For example, if the error is showing up while using the Wi-Fi connection, try accessing the website using your mobile data.

2. Restart your Internet modem or Router

Even if you believe your internet connection is fine and working, the modem may have corrupt DNS settings, that could be triggering the ‘ERR_NAME_NOT_RESOLVED’ error.

To flush these corrupt settings out, it would be advisable to reboot or restart your network device for a quick and simple solution to this error. All you need to do is,

  • Press the power button to turn off the modem. Wait until the LED lights stop blinking.

3. Flush your Browser History

One of the most common and simple troubleshooting steps for any kind of network issue is to flush out your complete browsing history. This is because browsers are designed to store a website’s temporary files, known as cache files, to provide a better user experience. However, over time, these cache files may get corrupted which can trigger the ‘ERR_NAME_NOT_RESOLVED’ error.

Therefore, it is always recommended to clear or delete your browsing history from time to time.

9. Disable DNSSEC for your Domain

Sometimes, an issue in the website’s DNS records can also trigger an err_name_not_resolved error. And if the website you are trying to access is not yours, there is nothing much you can do from your side.

But if you are the admin of the website, try disabling the DNSSEC for your domain. This is an additional security layer that protects your DNS records from access from unauthorized users. Due to this extra layer of security sometimes it also doesn’t allow the domain to propagate properly, resulting in triggering err_name_not_resolved error.

To check whether your website has DNSSEC enabled or not, you can run an online “WHOIS” search tool.

All you need to just enter your domain name and hit the search button.

If the DNSSEC status came out to be signed, then you are required to disable it. You can do this by logging into your Domain registrar account or through your hosting dashboard (If they provide domain along with web hosting).
