In my experience, that was due to the corporate firewalls' default rule of
disallowing outbound connections. Port 80 can be deep-packet-inspected to
confirm it's HTTP, and 443 can be confirmed to be SSL, and so everything
else was shut down. So everything had to be delivered over those, or it
failed. In my world, that means that IoT devices talking custom protocols
over SSL have to use 443 to the datacenters because the corporate firewall
people won't allow anything else out. And if you can't demo it from the
"guest" network at a company, you won't make any sales there.
OTOH, fq_codel should hash them out separately based on the destination IP
and source ports as separate connections. Not separable into a QoS bucket,
but at least able to pry apart the streams for fairness...
