The operating system is much more than the icons, and web browser we all see. It's made of multiple tasks and processes working together to provide the best experience possible. There are processes and tasks for the display, so that we can see the content, Internet connection, so that we can browse the Internet, sound, so that we can listen to what we open, and more. It is possible that a system process that stopped working or got stuck, or an unresponsive program/application is the reason why you get the ERR_NETWORK_CHANGED error message in Google Chrome.
In order to fix this error, the first course of action is to restart your device. Turn it off, and turn it back on after a few minutes.
Virtual Private Network software, or VPN is being used a lot nowadays. The way it works is that your device connects to a remote server anywhere in the world, owned and maintained by the VPN service provider. When connected to it, your device assumes a different identity, as its IP address (ID) as well as other settings are changed, ensuring that your online presence cannot be tracked, and your privacy is protected. Even though it's famous for protecting your privacy online, VPN software can sometimes interfere with the web browser and cause this error to appear in Google Chrome. Maybe the VPN server itself may have issues with its IP address or DNS settings, or the VPN app that's usually required to be installed on your device damaged operating system files accidentally.
If you have any VPN software installed in your device, uninstall it from your device, and check if that fixes the problem. If removing the VPN software did fix the problem, you can install it again, and check if the problem reappears.
The task of your modem and router is to ensure that the Internet connection you receive from your ISP is equally distributed to all your devices, throughout your home, while ensuring that unauthorized access is impossible. Like every piece of technology, the modem and the router can stop sharing the Internet connection, and break. Maybe the culprit for this error is not the device itself, but the router (or the modem, if you have one). It may be temporarily frozen (stuck), or completely broken.
To verify if the modem or the router, or both are the culprit, restart them. An effective way to restart them is by unplugging it from the power outlet and plugging it back in after a few minutes. In the meantime, restart, i.e. close and reopen the device's web browser, too.
Note: If you are not sure how to close (quit) an app, feel free to consult the how to close (quit) programs/applications guide.
Every time you connect to a Wi-Fi network, aside from saving the password, you save other instructions, too. One such instruction is connecting to that network automatically every time you turn the Wi-Fi on. Consider forgetting the Wi-Fi network as another way to fix this issue. All you need to do is to remove the Wi-Fi network from your mobile device's saved Wi-Fi passwords list, i.e. "forget" the network, and reconnect to it.
To "forget" a Wi-Fi network, follow the below-mentioned steps:
After you have "forgotten" a network, reconnect to it.
