Ok.  The way WL uses openssl is somewhat broken [1], in ways that can
be worked around by setting ssl-certificate-verification-policy to a
large value.  I haven't heard of any problems with gnutls, though I
haven't used it.  If you've tried both, then it's probably not a
problem with the ssl backend.  Can you open the connection to the
server using s_client or gnutls-cli directly on the command line (the
command that WL uses to open an ssl connection is assembled by the
code in ssl.el)?  Can you connect to the same server without ssl, just
to make sure I'm not barking up the wrong tree?

[1] openssl's s_client was meant as a debugging tool, not a backend
for other applications, and so the certificate verification semantics
are a bit unfortunate, see a three from the end of June entitled
"Auto-plugged off?"  I hope to do something about this at some point,
but probably not until after my thesis gets written.
