Windows: Add exceptions to the firewall

It may happen that your firewall blocks applications that do not pose a security risk. In this case, you can manually add an exception and then use the application as usual. You can find the corresponding options in the Control Panel under "System and Security".

Adding an exception to the firewall

The firewall is software that monitors incoming and outgoing network connections. In case of a possible threat from malware, the firewall interrupts the connection. It can always happen that a firewall blocks requests even though they do not pose a security risk. In this case, you can add an exception to the firewall to allow the connection. Individual firewall settings can also help better identify malicious software. Before adding exceptions, make sure that they are really trusted sources.

1. Open the menu and go to Control Panel.
2. Click "System and Security".
