Do you actually use a proxy though? That dialog just means "Don't
maintain my own proxy settings, use whatever the host proxy settings
are". Which you'll find in System -> preferences -> network proxy.
That's your proxy server address, if indeed there is one.

So maybe there is no proxy?

If you go to http://www.whatsmyip.org/more/ do you see "Proxy: No
Proxy or Invisible Proxy Used "? In addition is there an
HTTP_X_FORWARDED_FOR which may indicate a proxy is in use.

Firstly I'd make sure you're allowed to use bittorrent on the networks
you're on. Most corporate and education networks (rightly or wrongly)
block bittorrent where I am, proxy or not.
