Hello Rachel S,


The Domain Name System (DNS) is used to locate the IP address of a specific website domain name. It creates web browsing possible, specifically with over a billion websites on the Internet.

However, there might be circumstances when the system cannot locate the IP address, resulting in an ERR_NAME_NOT_RESOLVED DNS error. There are several possible causes, but the "ERR_NAME_NOT_RESOLVED" error occurs when a browser can't locate the IP address that hosts the domain name you wish to visit. Here are some possible causes for the error to occur,

• Cached data
• Network settings
• Enabled DNSSEC
• Antivirus software misconfiguration or Firewall.
• Browser settings.

Thus, In order to fix the error, you can follow the steps below,
