Encountering the error message ERR_NAME_NOT_RESOLVED in your web browser indicates that the browser couldn't find the IP address of the server you're trying to connect to using its domain name. This problem can stem from several factors, including issues with the Domain Name System (DNS) server, poor internet connection, or misconfigurations in the network settings. In this article, we'll explore the causes of this problem and offer steps to resolve it.

Causes of the ERR_NAME_NOT_RESOLVED Problem

1. DNS Server Issues: DNS servers translate human-readable domain names (e.g., www.example.com) into IP addresses that computers use to establish connections. If a DNS server is unavailable or experiencing other issues, your browser can't perform this translation.

2. Misconfigured Network Connection: Sometimes, the error may be caused by incorrectly configured internet connectivity on your device.

3. Local DNS Cache or Hosts Files: Computers and browsers cache DNS information locally to expedite future accesses to websites. If this information becomes outdated or corrupted, it can result in the ERR_NAME_NOT_RESOLVED error.

How to Fix the Problem

1. Check Your Internet Connection: Ensure that your device is properly connected to the internet. Try accessing a different website, for instance, to verify your connection.

2. Clear DNS Cache: You can clear the DNS cache on your computer, which may help resolve the problem. The process varies depending on your operating system.

3. Change DNS Servers: If the issue persists, try changing your device's DNS server settings. You can use public DNS servers such as Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).

4. Check the Hosts File: The hosts file may contain static mappings of domain names to IP addresses. Ensure that there are no incorrect or outdated entries in the hosts file on your device.

5. Restart Your Router or Modem: Sometimes, restarting your internet device can resolve DNS-related issues.

If none of these steps help, the problem may lie with the web server or your internet service provider. In such cases, you can contact technical support for further assistance.

The ERR_NAME_NOT_RESOLVED error can be frustrating, but in most cases, it can be resolved using the simple steps outlined above. The key is to take a systematic approach to diagnose and address the issue, allowing you to quickly get back to browsing the internet.
