Hello@Sullivan718 ,
Welcome to our community.
If your router or app does not support direct URL blocking, you may need to check for firmware updates or consider using a TP-Link router model that supports more advanced parental controls.
Here are some steps you can try to block specific websites:
1. Verify Parental Control Settings.
2. Clear Cache and Cookies: On the devices you want to restrict, clear the browser's cache and cookies. This can help ensure that previous access attempts do not bypass the parental controls.
3. Disable VPN Software: Make sure any VPN connections are disabled on the devices you are controlling, as VPNs can bypass parental controls.
4. Disable Secure DNS Feature: On the controlled devices, open the browser settings and go to Settings → Privacy, search, and services → Use secure DNS. Turn off the secure DNS feature, as it may allow users to bypass website blocking.
