I'm having the same exact problem at work.

It looks like a problem related to IPv6 support. Could you check if you
have IPv6 in the i386 kernel?

I found just one thread abut this in the squid mailing lists and on
linux the solution sems to be enabling IPv6. (can't find the url right

I suspect squid 3.1.6 is trying to, for some reason, uses some IPv6
feature to perform CONNECT requests used to transport https.

My solution for now has ben reverting to the previous (3.1.4) version of
the squid port waiting to find a fix for this.
