There isn't a lot of information here and what there is raises
questions. For example, the error message here doesn't match the PHP
code supplied.

But "Connection refused" is generally a socket error due to handshake
failure in TCP setup. This would be caused by firewalls, bad dns
setup, bad routing, bad NAT config, angry server aborting connection.
A packet trace from 'wireshark/tcpdump' would reveal what is going
on and who is responsible.

But it seems likely you have some DNS hacks/breakage. {admin,streams}.
ourstation.org do not resolve to anything so either this is more
misleading info or you have DNS hackery in play.

Finally, 'curl --libcurl' will help you write better setup code.
