The configuration looks correct, what else could I check?
Your curl reports an SSL error, so you're using its native SSL support instead of stunnel client.
Remove all non-essential configuration file options. If you don't understand an option, just leave it at its default instead of using a random value.
Collect stunnel debug logs on both ends. Hopefully this will help you find the solution by yourself, without asking 536 subscribers of this mailing list for help.
