Ssl exception while not using ssl connection?

I am using the latest wildfire IM server, and have a simple client.

It connects to the server well in the first time.

But in the second and subsequent time, the server complains the follwoing exception; Unrecognized SSL message, plaintext connection?

I don’'t quite understand this, because I am using SSL at all? Does anyone experience the same problem? How to solve this? Thanx.
