Chrome ERR_CONNECTION_TIMED_OUT — What It Means

Seeing ERR_CONNECTION_TIMED_OUT in Chrome? Learn whether the problem is your connection, the website, or your browser settings — and how to fix it.

Which best describes your situation?

Only one specific website

The problem is on that site's end, not your connection.

Next step: Check downdetector.com to see if others report the same site down. Wait 5–10 minutes and try again.

Multiple websites or everything

Your internet connection or DNS has an issue.

Next step: Restart your router (unplug, wait 30 seconds, plug back in). If that fails, open Command Prompt and run: ipconfig /flushdns

Just started happening in the last hour

A recent browser extension, update, or network change is interfering.

Next step: Open the same URL in an Incognito window (Ctrl+Shift+N). If it loads, a Chrome extension is the culprit — disable them one at a time.

Frequently asked questions

Is ERR_CONNECTION_TIMED_OUT a problem with my computer or the website?
It can be either. The error means Chrome gave up waiting for a response from the website's server. This could be because the server is overloaded or down, your internet connection has a problem, or something between you and the server (firewall, DNS, router) is blocking or slowing the request.
The site works on my phone but not my computer — why?
This is a strong indicator the problem is on your computer, not the website. Your phone likely uses a different network (mobile data vs Wi-Fi) or different DNS settings. The most common cause in this scenario is a misconfigured firewall, a browser extension, or a local DNS issue on your computer.
Will clearing the DNS cache fix it?
It fixes the problem in a meaningful number of cases. Stale DNS records can point your browser to an outdated IP address for a website, causing connection failures. Running 'ipconfig /flushdns' in Command Prompt forces Windows to look up the fresh address.
Could my antivirus or firewall be blocking the connection?
Yes. Security software sometimes incorrectly flags legitimate websites and blocks connections to them. To test this, temporarily disable your antivirus's web protection (not full antivirus) and try the site again. If it loads, add the site to your antivirus's allowlist.
