HTTPS-traffic skipping proxy


I have a Firebox and have set up https-proxy for any-trusted to any-external.
As a test I have a any-any below the proxy rule allowing outbound traffic but logging it. And I'm wondering why I see https traffic on port 443. It seems legit, but somehow it skips the proxy.

Any idea what I might go wrong?

    Perhaps it is UDP port 443 and not TCP port 443?
    HTTPS is TCP port 443.

    Care to post a sample Traffic Monitor log message showing this?

    Sounds like QUIC protocol and a Chrome browser
