The ERR_CONNECTION_FAILED error in Google Chrome means the browser tried to connect to a website but the connection attempt was completely blocked or refused before it could even begin. This is different from a website being down — it usually points to a problem on your end, such as a misconfigured network, overzealous firewall, corrupted DNS settings, or a conflicting browser extension. The good news is that most causes of this error can be resolved in a few minutes without any technical expertise.

When to Call a Professional

Contact your Internet Service Provider (ISP) if the error persists across all browsers and all devices on your network after restarting your modem and router — this points to an ISP-side outage or account issue. Seek IT support if the error only happens on a work or school computer where you do not have administrator access to change firewall or DNS settings. If your computer has malware that is redirecting or blocking connections, run a full malware scan with a tool like Malwarebytes, or consult a professional PC repair technician.

Frequently Asked Questions

What causes ERR_CONNECTION_FAILED in Chrome?
ERR_CONNECTION_FAILED is most commonly caused by a misconfigured proxy or VPN, a firewall or antivirus program blocking Chrome, corrupted DNS cache, stale Chrome socket connections, or a faulty browser extension. Less commonly, it can be caused by a corrupted Chrome installation or an issue with your ISP's network.
Does ERR_CONNECTION_FAILED mean the website is down?
Not necessarily. ERR_CONNECTION_FAILED means Chrome could not establish a connection at all, which almost always points to a local issue on your device or network rather than the website being down. If the website were down, you would typically see a different error like ERR_NAME_NOT_RESOLVED or a server error page. Test the same website on a different device or network to confirm whether the site itself is the problem.
Why does ERR_CONNECTION_FAILED only happen on one website?
If the error only affects one specific website, that site may be blocking your IP address, or your local DNS is failing to resolve that particular domain. Try clearing your DNS cache (ipconfig /flushdns on Windows), switching to a public DNS like Google's 8.8.8.8, or using a VPN to change your apparent location. It is also possible that particular website is down or blocking traffic from your region.
How do I fix ERR_CONNECTION_FAILED on Android or iPhone Chrome?
On mobile, start by toggling Airplane Mode on and off to reset the network connection. Make sure you are not connected to a VPN. Go to Chrome Settings > Privacy > Clear Browsing Data and clear the cache. If on Wi-Fi, try switching to mobile data to see if the problem is network-specific. Restart the Chrome app completely, and if the problem persists, uninstall and reinstall Chrome from the App Store or Google Play Store.
Will resetting Chrome fix ERR_CONNECTION_FAILED?
Resetting Chrome can fix the error if it is caused by corrupted settings, a bad extension, or misconfigured proxy settings within Chrome. To reset, go to chrome://settings/reset and click 'Restore settings to their original defaults'. Note that this will disable your extensions and clear your startup pages and search engine settings, but it will not delete your bookmarks or passwords. If the error is caused by a network or firewall issue outside of Chrome, a reset alone will not fix it.
