I often enable and disable parental control for to test the router. When i enable TOR, VPN and Literal IP addresses block and then disable them, many times i have this problem. And i must to do the reboot.
I disable parental control only for the home pc profile, not at router level.
Sometimes i can’t surf in internet, other times there are sites like “pcwrt.com” that doesn’t work and other times can’t load images like the screenshot example that i’ve posted above.
