website browser errors

This Site Can’t Be Reached

Compare your connection with a server-side website check, then separate one-site problems from wider browsing failures.

Check Site and Connection ↓

Measurements describe the endpoint and test shown. HTTP timing is not network-layer packet loss or a direct measurement of your router, WiFi radio or ISP.

Your guided check

Observe. Compare. Take the next step.

Public hosts only. Query parameters and fragments are removed. Leave blank to use connection checks and your answers.

The check contacts our endpoints and Cloudflare / Google public DNS services. They receive your IP and the public hostname being queried. Test privacy

Read the smaller error code

This site can’t be reached is a broad message. ERR_NAME_NOT_RESOLVED, ERR_CONNECTION_TIMED_OUT and ERR_CONNECTION_RESET describe different failures reported by your browser. Select the code you see, not a suspected cause.

Compare one site with other sites

If unrelated sites open, a complete loss of internet access is less likely. Check spelling and compare the affected site on mobile data or another browser.

Interpret a server check in its own location

A server reports its own DNS, TLS or HTTP failure class. It does not reproduce your browser’s DNS, VPN, account or regional path. A 403 or 500 proves an HTTP response arrived, not that the site works normally.

Frequently asked questions

Should I ignore a certificate warning?

No. Do not bypass certificate checks or enter credentials on a connection marked unsafe.

Why can your server reach a site that I cannot?

The resolver, network route, region and browser environment can differ.
