Chrome ERR_NAME_NOT_RESOLVED: hostname resolution failed

Google defines this Chrome page-loading code as a hostname that does not exist or now resolves differently; verify the name and DNS path before browser reset.

Applies to: Google Chrome page-loading context on WindowsReviewed: 2026-09-17

What it means in this context

Google Chrome Help describes ERR_NAME_NOT_RESOLVED as a hostname/web address that does not exist or has a different IP address. This record is specifically for Chrome’s page-loading code; it does not prove the Windows DNS client itself is broken.

Start here
  1. Verify the URL/hostname spelling.
  2. Try another website in Chrome.
  3. Try the same hostname in another browser.
  4. Run nslookup for the hostname if the failure appears system-wide.
1

Diagnose DNS rather than reinstalling Chrome first

Low risk

Why: The code is about hostname resolution, so a DNS comparison is more targeted than browser reinstall.

  1. Run nslookup for the hostname.
  2. If other hostnames resolve but this one does not, consider a domain/DNS-record problem.
  3. If many hostnames fail across browsers, follow the Windows DNS-resolution guide.
2

Flush the Windows DNS cache only when stale local resolution is plausible

Low risk

Why: Microsoft documents /flushdns for DNS name-resolution troubleshooting.

  1. Open Command Prompt or Terminal.
  2. Run ipconfig /flushdns.
  3. Retry the hostname.
ipconfig /flushdns

When not to use this record

If only one domain fails across multiple devices/networks, the domain or authoritative DNS may be the issue; do not keep resetting the local PC.

If it persists

Use the DNS-resolution guide for system-wide failures or Chrome’s general page-loading guide when the error changes to a different network code.

GuideChrome page-loading network errors on Windows: separate browser, DNS and network layers

Use Chrome’s exact error code and a cross-browser comparison before clearing data, disabling security tools or resetting Windows networking.

ErrorERR_CONNECTION_REFUSED — Chrome ERR_CONNECTION_REFUSED: the destination did not accept the connection

Google describes this as the page not allowing Chrome to connect or the page being blocked; prove whether the failure is destination-specific before local resets.

ErrorERR_CONNECTION_RESET — Chrome ERR_CONNECTION_RESET: the connection was interrupted

Google says this error means something interrupted the connection; unstable networking, VPN, outdated browser or security software can be involved.

ErrorERR_CONNECTION_TIMED_OUT — Chrome ERR_CONNECTION_TIMED_OUT: the destination took too long to connect

Google says the page took too long to connect; the local connection may be slow or the destination may be busy/unreachable.

ErrorERR_NETWORK_CHANGED — Chrome ERR_NETWORK_CHANGED: the active network changed during loading

Google defines this as the device disconnecting from a network or connecting to a new one while the page is loading.
