Proxy issue

[SaratKumarM]

I am using scribe library to write a sample Facebook application :). I am trying to access "facebook graph" api using scribe utility . The main problem is that we were unable to access https://graph.facebook.com using the https protocol. I am behind a firewall & I mention the proxyserver details but I am unable to connect facebook graph api :)

I see below exception :

Your proxy is returning bad request. Perhaps it's because of SSL? I'm not sure about this but you should definitely talk with your network administrator, this is an issue on your network and not on scribe, sorry.
