[yocto] Working behind a Palo Alto firewall/proxy

[Mark Hatle]

I've had a customer with a similar problem.  The way they resolved it was to
download the certification from their proxy and add it to their system as a
known certificate.

Sorry I don't have any more details then that, but maybe that can spark someone
who knows the actual steps to be able to comment.
