How to Fix ERR_NAME_NOT_RESOLVED

Browser DNS name resolution troubleshooting
ERR_NAME_NOT_RESOLVED

Quick answer

ERR_NAME_NOT_RESOLVED means your browser could not turn the website name into an IP address. Flush the DNS cache, change to a public DNS server, disable Chrome's prefetch and check the URL.

What does “ERR_NAME_NOT_RESOLVED” mean?

The DNS lookup failed, so the browser does not know where the website is.

What causes it?

  • DNS server not responding
  • Wrong URL
  • Old DNS cache
  • Firewall blocking DNS

Steps to try

Stop when the issue is resolved.

  1. Check the URL.
  2. Run ipconfig /flushdns.
  3. Set DNS to 1.1.1.1 / 1.0.0.1 or 8.8.8.8 / 8.8.4.4.
  4. Restart the router.
  5. In Chrome, go to chrome://net-internals/#dns and clear host cache.
