What error?

It would be helpful if you could get the exact error and exat line.

The only difference in principle between ssl and non-ssl is that the
server and client communicate over ssl channels instead of over ordinary
tcp sockets.

I haven't tested ssl at all during development of the 2.4.* line.  It
would not surprise me if ssl had broken somehow along the way.  Drop
back to a version where it works for sure (the 2.2.* series springs to
mind!).  Then try and locate a version change where it stops working.

One of the things that did happen in 2.4.* was that the initial
communications became more "unix like", with a listening socket 
splitting off communication channels on a fixed port as necessary.
That may be implicated if there is some ssl breakage.

Let me know what you find out.

(cc'ed to andres who did the ssl work and knows all about it).
