Firewall connection helps to protect your computer from security threats. Windows 10 has a built-in app Windows Defender Security Center for protecting your system. It has multiple options like firewall & network protection, antivirus, app control and Edge browser control settings. By default Windows will enable protection for all private and public networks available on your computer. When you disable firewall, Windows will send an alert and ask you to enable it for protecting your computer.
Why You May Need to Disable Firewall?
Windows Defender has an option for allowing or blocking individual apps with firewall. If you have wrongly blocked the app that needs internet access then you will see access error. Generally browsers like Chrome will show errors like ERR_CONNECTION_CLOSED, connection reset or refused to indicate something blocks your network.
The indicated solution from Google is to check the firewall settings and allow Chrome browser to send and receive data. So, it is necessary to disable the firewall settings before you troubleshoot the internet connection problems.
