Every day you use Google Chrome to access thousands of websites either for personal or work issues, and when you visit a website, your computer connects to a server to show you the page, but sometimes this process has errors.

What is ERR_NETWORK_CHANGED?

Sometimes when there is a problem with your computer, you may find this error, however, even when you try to reload the website, the connection is impossible.

This error may be associated with your hardware (such as modem, router or network card failures) as well as software (viruses, service errors, etc.).

That’s why on this post I will show you some of the best ways to fix this error quickly.
