Greetings Rick,

I wouldn't worry too much about the TransportProxy line in your state
file. That line is there in case you ever decide to start up an obfs2
listener ever again: it has noted down the IP:PORT it used to use, so
that it binds in the same address the next time you start it up (which
in your case is 'never').

However, the fact that obfs2 still appears in your bridge's page in
globe.torproject.org is more troubling. Is it still there? If yes, how
did you deprecate obfs2? Did you restart Tor or did you do a SIGHUP?

Feel free to send me a private mail with your IP:PORT and I can try to
look into this (see if your bridge is still advertising obfs2 support
to the bridge authority).

Cheers!
