Looks like your configuration is incomplete. Check  the sample stunnel.conf file in the stunnel distribution. Read the man page. Post your log file.

Try adding lines like these before [Router]

sslVersion = SSLv3


# Authentication stuff, try 0 for test
verify = 0

CApath = /your/CAcerts/path

debug = 7
output = stunnel.log

Subject: [stunnel-users] No SSL handshake between stunnel in client mode and SSL server

Hi guys, 
I have a quick question. I am trying to use stunnel in client mode to encrypt traffic going to my server.
Basically, I have a server which listens for SSL connection. And I have a client which can not do SSL but it needs to communicate with server over SSL. 
I setup stunnel in client mode to accept unecrypted traffic from client and redirect it to server over SSL. I checked TCP traffic with WireShark between stunnel  and my server and I can see that there is no SSL handshake, stunnel makes TCP connection with server and sends some TCP packets but I expect to see SSL handshake.
My stunnel conf file is here:
accept =
connect =
Can you please comment on this?
Best regards,
