Error guide / ERR_CONNECTION_RESET

ERR_CONNECTION_RESET error

ERR_CONNECTION_RESET means the connection opened but then broke off suddenly in the middle of the exchange. The browser started talking to the server and the link was cut. Unlike a timeout or a refusal, the connection did exist here, but it was dropped halfway through.

What causes it

Most often the reset comes from the server or the gear between you and the site: overloaded hosting, an aggressive firewall, flaky Wi-Fi, or ISP filtering. Sometimes antivirus software or a VPN that inspects traffic is the culprit.

How to fix it

1. Reload the page, since a reset is often a one-off and clears on the second try.
2. Check your own link: restart the router, try a cable instead of Wi-Fi, or switch to mobile data.
3. Turn off any VPN, proxy, and extensions, and pause antivirus that scans HTTPS.
4. Clear the cache and flush the browser DNS, then open the site in incognito.
5. If the site is yours, check server logs and the firewall (CSF/mod_security) for mass resets and reduce CPU load.
6. Make sure the web server's connection limits and timeouts are not set too low for your traffic.
