Norton ConnectSafe DNS not working after configuring in PC

Hello , Norton ConnectSafe is not working for me.

I am on Static IP address

I have followed the instructions as mentioned in the page -https://dns.norton.com/homeuser.html

I have put the following DNS (Configured PC)
199.85.126.20

199.85.127.20

But, it doesn't block any porn sites.

 Please help.
