How to fix ERR_CONNECTION_TIMED_OUT

Chrome shows ERR_CONNECTION_TIMED_OUT when it tried to connect to a site and nothing came back before the time limit. Other browsers word it differently, for example “The connection has timed out”, but the cause is the same.

What it usually means

Your browser sent a request, and no answer arrived. That happens when:

the site’s server is down or too busy to reply;
a firewall, security program or router is blocking the connection;
your internet connection is slow, unstable, or not working;
a proxy or VPN is getting in the way;
your device has a wrong or out-of-date address for the site (a DNS problem).

Fixes to try, in order

Check if the site is down for everyone. Run a check. If the result says Timeout or Down from several places, wait and try later. The problem is not on your side.
Test another site. If nothing loads, restart your router and check your connection.
Try another network. Use mobile data on your phone. If it works there, the problem is your home network.
Disable any VPN or proxy, then reload.
Pause your security software or firewall for a minute to test. Turn it back on straight afterwards.
Flush your DNS cache. See how to flush DNS.
Clear your browser’s cache and cookies, or open a private window.
Switch to a public DNS server such as Google (8.8.8.8) or Cloudflare (1.1.1.1) in your network settings.

If you run the site

A timeout from many places means the server is overloaded or unreachable. Check that the server is running, that port 443 is open in your firewall, and that your host is not having an outage. A speed test shows whether the server answers slowly rather than not at all.

Check a website now

Is it down for everyone, or just you? Paste an address and we test it from fifteen places.
