XML serialisation error when connecting to XMPP server

I have an instance of OpenFIre up and running and all is pretty smooth. I can connect to it via Spark as well as a variety of app.

When I wrote my app using the trial version of the Matrix SDK, the client connected perfectly. I am trying to move over to Sharp.XMPP and yet, whenever I try to connect to the server, I get the following error message :

The XML stream could not be negotiated.

When I drill down, I get to the folllwoing inner exception

{"'�', hexadecimal value 0x15, is an invalid character. Line 1, position 1."}

There seems to be some issue with the response encoding that Sharp.XMPP is expecting.

Does anyone have any idea how to fix this?

Are you trying to connect to an old-style SSL port (usually 5223) with a client that expects to do StartTLS (usually on 5222)?

(0x15 is the TLS content type for "alert", which is likely the response when parsing something that is not TLS.)
