The compression is not recommended with TLS because of the CRIME or 
BREACH attacks.
 From stunnel v 5.44 in Windows the zlib compression is not supported.
So you should remove the option:
compression = zlib

If you want to use  this compression, please place the file zlib1.dll 
(from the previous version) in the stunnel / bin directory.

Best regards,
