This is not an STunnel issue but an OpenSSL libraries/defaults issue.
Solved!
It is an Ubuntu specific problem.
Solution is in here (last post):
https://bugs.launchpad.net/ubuntu/+source/stunnel4/+bug/1989387
Worked immediately after the proper configuration changes.
Almost 1 year of trouble and searches for a stupid OS bug...
Nothing wrong with stunnel, nothing wrong with openssl, nothing wrong with my settings...
Cheers! Stefano
