When you see the ERR_NETWORK_CHANGED error message in Google Chrome, it means that your browser has detected a change in your network connection. This can occur due to various reasons such as switching networks, loss of internet connection, or changes made to your router's settings. The error is typically caused by a mismatch between the URL's network location and the current network settings. To resolve this issue, try the following steps: Clear the browser's cache and cookies, Disable any extensions that may be interfering with the network connection, Restart your router, Check if your network settings are set to obtain an IP address automatically, or use a static IP address if available. If the issue persists, consider resetting Chrome to its default settings.
