What Does ERR_CONNECTION_RESET Mean?

The ERR_CONNECTION_RESET error appears when you try accessing a website, but Google Chrome fails to establish a connection. As a result, the connection is “reset,” which means that Chrome can’t connect to the website’s server, and the server can’t send data to your web browser.

In most cases, while you can access most websites, this error may prevent you from accessing specific websites.

Our research has revealed that the ERR_CONNECTION_RESET error usually indicates a client-side connection issue, which can occur due to the reasons listed below.

  • A corrupted web browser cache.
  • A problem with your proxy settings.
  • Incorrect or corrupted TCP/IP configuration.
  • A problem with your Virtual Private Network (VPN). Try disabling your VPN to fix the error.
  • A third-party firewall or anti-virus program blocks the connection. Try disabling your anti-virus or firewall program.
