ERR_CONNECTION_RESET is an error indicating that the website you are trying to visit cannot establish a stable connection. This error can be caused by registry changes or network settings. This error sometimes only happen on certain websites and can be fixed easily with proper troubleshooting.

This is a common error on the Internet, mainly in the Google Chrome browser. There are various reasons for this error in your browser including the DNS probe would not stop and other causes mentioned in the error message.

What is ERR_CONNECTION_RESET?

Usually this error that comes with a 101 code is mostly common in Chrome. However, Firefox, Microsoft Edge and other browsers also display similar error message like this. Unlike HTTP error messages, “ERR_CONNECTION_RESET” does not directly indicate whether the problem is caused by the client, server or network.

Technically, when you connect to the correct website, your browser only receives a FIN packet instead of a regular response packet. It is used by TCP (Transmission Control Protocol), the standard Web Transport Protocol, to notify the client when the connection is terminated. However, the FIN packet is usually preceded by a connection established earlier within a certain period of time, which is not the case with the “ERR_CONNECTION_RESET” error.

How to Fix ERR_CONNECTION_RESET

Solution 1 – Checking the Internet Connection

If Google Chrome browser shows an ERR_CONNECTION_RESET message, you must first check your Internet connection. When using cables, make sure that the network cables are not damaged. If you are using WiFi, the connection may change due to various problems.

Remember that the wireless icon on the taskbar does not mean that your computer can connect to the Internet. An easy way to check your Internet connection is to check it with another device connected to the same network.
