How to Fix ERR_NAME_NOT_RESOLVED

The ERR_NAME_NOT_RESOLVED error is your browser's way of saying it cannot translate the website name you typed into a computer-friendly IP address. If the browser can't find the IP address, it can't load the page.

What Causes This Error?

This is almost always a client-side (local) issue relating to your DNS settings, rather than the website itself being offline. Common culprits include:

  • A simple typo in the web address.
  • A stale or corrupted local DNS cache on your computer.
  • Issues with your router's configuration.
  • Your Internet Service Provider's (ISP) default DNS servers are down or experiencing outages.

How to Fix ERR_NAME_NOT_RESOLVED

1. Double-Check the URL

Ensure you didn't accidentally type google.con instead of google.com. A misspelled domain name simply doesn't exist to be resolved.

2. Flush Your DNS Cache

Your computer saves IP addresses to load websites faster next time. If that saved data is outdated, it throws an error. Clearing this cache forces your computer to look up the correct address.

  • Windows: Open the Command Prompt as Administrator, type ipconfig /flushdns, and hit Enter.
  • Mac: Open Terminal, type sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder, and hit Enter.

3. Change Your DNS Servers

If your ISP's DNS servers are struggling, bypassing them is the best fix. Change your computer or router's DNS settings to point to free, highly reliable public servers like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1 and 1.0.0.1).

4. Reboot Your Router

When in doubt, turning your modem and router off for 30 seconds and turning them back on will clear temporary network snags that block DNS lookups.
