I setup a calendar so that fortnite could only work during a specified interval.
It works fine.
However, i noted that other sites/hosts are also subject to the same calendar restrictions. Notably Steam.
The only site I entered for the fortnite block was epicgames.com
why would this also cause Steam to be blocked?
You can view the logs to find out what domains were blocked when you use Steam: click the Access Control icon, then click “View Logs” link on that page. You can switch between Chart view and Raw view. The Raw view gives more details about why a site is blocked.
