The problem is phttpget or the proxy, depending on the point of view.

Some proxies have (had) problems with the pipelined http requests that 
phttpget seems to use.

apt (Debian/Ubuntu) has, too - but they can be disabled altogether 
there.

IMO, there should be an option to use wget instead of phttpget. Or at 
least disable the request-pipelining.
There was a PR with patches floating around to make freebsd-update use 
wget, but it never gained traction.

Also, didn't phttpget have problems with proxies needing authentication?
I usually have authentication at the proxy disabled for *.freebsd.org 
for this reason.
