Same here, then I noticed the server it connects to has an expired certificate, maybe
windows just connects despite this and wine is more strict? I emailed them about it some time ago,
but seems they haven't found the time to replace it with a correct cert.
% openssl s_client -connect 95.xxx.xx.xxx:989
CONNECTED(00000003)
