This just means that the client hasn't sent a CONNECT message yet, so
the broker cannot know the client id.

There is no way that the use of SSL_pending() is causing a disconnect.

I imagine that what is happening is that your socket connection
succeeds, but the SSL connection does not complete immediately. This
leads on to SSL_pending() being called. At the same time, your
connection must fail (or possibly have timed out) in order for the
Socket error to be generated.
