There are a few platforms and services where using CleanBrowsing can be problematic because of how DNS is supported. Below is a list of the platforms we know of:

Comcast Xfinity

If you are trying to use CleanBrowsing on Comcast Xfinity and it doesn’t seem to be working, the reason might be their Protected Browsing option hijacking your DNS. It prevents any other DNS from working, except their own.

We have prepared a guide to help provide you the best options available.

Avast

Avast! Anti-Virus, which includes a “Real Site” protection offering which Hijacks your DNS.

Go to Settings and disable this component for CleanBrowsing to work. You won’t lose any protection as all our filters include the security-filter by default (that blocks phishing, malware, etc).

AT&T

Depending on the router AT&T provided, you might not be able to change DNS in their router.

EERO Secure

If EERO Secure is enabled on your EERO device you will have an issue configuring CleanBrowsing. When this feature is enabled all non-VPN traffic is tunneled through their own DNS provider. This will hijack all network traffic, overriding whatever DNS is set on your network.
