Did you follow all the instructions on the airpsy thread?
This is what I get on my setup:
pi@pi_3:~ $ sudo piaware-status
PiAware master process (piaware) is running with pid 515.
PiAware ADS-B client (faup1090) is running with pid 641.
PiAware mlat client (fa-mlat-client) is running with pid 632.
Local ADS-B receiver (dump1090-fa) is running with pid 508.dump1090-fa (pid 508) is listening for connections on port 30005.
faup1090 is connected to the ADS-B receiver.
piaware is connected to FlightAware.dump1090 is producing data on localhost:30005.
Your feeder ID is xxxxxxxxxxxxxxxxxxx (configured at /etc/piaware.conf:9)
If that worked before… you need to reboot the remote system somehow.
