ERR_NAME_NOT_RESOLVED is a common DNS resolution error in Google Chrome, typically caused by misconfigured or outdated DNS settings, a problematic network connection, or issues with the website's domain name. To resolve this issue, you can try the following steps:
1. Check your network connection and ensure it is stable and working properly.
2. Clear the browser cache and cookies, and restart Chrome in safe mode to disable extensions and themes.
3. Use a third-party DNS service like Google Public DNS or Cloudflare DNS, which can provide faster and more reliable DNS resolution.
4. Check the website's domain name and ensure it is properly spelled and formatted.
5. If none of the above steps work, try using the Chrome flag "--disable-web-security" to disable Web Security features, but note that this may compromise browser security.
By following these steps, you should be able to resolve the ERR_NAME_NOT_RESOLVED error and access your favorite website again.
