Speedtest.net (HTML5 version) doesn't work via squid.

Greetings, i've set up squid with HTTP/HTTPS inspection via CA certs. Pretty standard setup. All works as expected.

The only issue is when I go to speedtest.net I get the error saying that I have an AdBlocker that needs to be configured (see attached image). This only happens if I try to use their HTML5 test. If I use the "Legacy" Adobe Flash test, it works just fine.

/var/squid/logs/access_log shows the following denials:

I've tried adding these domains into the whitelist under ACLs, but that hasn't changed anything.

Anything else I can try?

Thanks for any suggestions!

Do you have pfBlockerNG installed also?

I do, but it's not enabled.

@JamesVA:

I do, but it's not enabled.

The DNSBL portion also?

I run squid also with MITM Non-Transparent and Certificates with proxy configured in Edge browser and if I disable pfBlocker and
the DNSBL portion I can run the HTML5 speed test's.

On the Cert's tab in Squid I run Intermediate instead of Modern and also Do not verify remote Certificate's due
to a problem's with my wife's work-site.
