Hello all,

I'm having trouble getting sites like Youtube, Network Solutions, and other HSTS sites to load consistently when I have DNS Content Filter turned on.  It was a lot worse when I had the ATT fiber router set as the ATP's DNS server.  That's now set to Level3, but these sites are still getting blocked 90% of the time.  What am I missing?

Thanks,
-John

    1)What's kind of your Profile ? Youtube will be classified as media-sharing.And they will block in BPP Profile.
    2)What's your FW version ? Does any UTM Feature enable ?
    3)Any message in log ?
    For DNS Content Filter. All inquiry traffic, Firewall must be NS.In this way, It can response redirect address we expected.
