NSA 2650 gen 6 not block proxy access (VPN browser)

Hi,
I enabled app control and I blocked all proxy access.
I blocked VPN in app control
SOnicwall NSA2650 app control is not working.
Browser with VPN incorporated such as epic privacy browser bypass the firewall and all rules.
I have already tried to enable dpi ssl but with no result

Make sure you blocked the Hacking/Proxy Avoidance Systems category in CFS policy.
Yes, of course I did it
But it not solves my problem.
Thank you
