Check the address and select Reload, then read the code at the bottom of Chrome's 'This site can't be reached' page. If one site fails, test it later or contact its owner; if several sites fail, confirm Windows is online and restart the modem or router. If the network works but Chrome alone fails, update and restart Chrome, test Incognito, and disable extensions one at a time before considering a Chrome settings reset.
Confirm the address has no typo, select Reload, and copy the code beneath This site can't be reached. ERR_NAME_NOT_RESOLVED, ERR_INTERNET_DISCONNECTED, ERR_CONNECTION_TIMED_OUT, ERR_CONNECTION_RESET, ERR_NETWORK_CHANGED, ERR_CONNECTION_REFUSED, and ERR_EMPTY_RESPONSE describe different failures.
2
Separate one failed site from many
Open a known-good site in a new tab and try the original address on another current device using a trusted connection. If only the original site fails, retry later or contact its owner; an empty response, refusal, timeout, or missing hostname can be server-side.
3
Restore the connection when many sites fail
Confirm Windows shows the intended Wi-Fi or Ethernet connection and Airplane mode is off, then complete any public-network sign-in. If other apps also cannot connect, restart the modem or router once and contact the ISP if the connection does not return.
4
Update and restart Chrome
Select More > Help > About Google Chrome and select Relaunch if offered; otherwise select More > Exit and reopen Chrome. Enter the same exact address and confirm whether the original code changes or the page loads.
5
Test Incognito and extensions
Open More > New Incognito window and enter the same address. If it loads, open More > Extensions > Manage extensions in the normal profile, turn extensions off, and restore them one at a time until the code returns.
6
Reset Chrome only after the scoped tests
If Chrome alone still fails across sites, select More > Settings > Reset settings > Restore settings to their original defaults > Reset settings. Google says bookmarks and passwords remain, but search engine, startup pages, pinned tabs, content settings, cookies, extensions, and themes can change; reload the address and verify the result.

If it does not work
For ERR_NAME_NOT_RESOLVED, recheck the hostname and ask the site owner whether the address moved. Do not change DNS globally for a misspelled or retired domain.
For ERR_INTERNET_DISCONNECTED or ERR_NETWORK_CHANGED across several sites, restore the Windows connection and finish any network sign-in before changing Chrome.
For ERR_CONNECTION_REFUSED or ERR_EMPTY_RESPONSE on only one site, retry later and contact the owner. The server may be rejecting connections or returning no data.
If a work device or network blocks the page, give the administrator the exact address and code. Do not disable the firewall, remove a managed proxy, or reset TCP/IP without their direction.
ⓘ Sources and verification
Checked against official documentation on . Scope: Windows.
Chrome uses This site can't be reached for several distinct errors. The code beneath it distinguishes a missing hostname, disconnected network, timeout, reset, refusal, network change, or empty response, so broad DNS and TCP/IP resets are not a universal first step.
