"Connection refused" means that pacat couldn't find the socket file of
the server. You can run "PULSE_LOG=99 pacat" to see where pacat tries
to find the socket, and compare it to "sudo netstat -lxp | grep pulse".
The latter command should show all socket locations that any pulseaudio
instance is listening on.

Setting default-server should be unnecessary. If libpulse can't connect
to the per-user daemon, it should automatically try the system-wide
socket location.
