Sorry, here is output of "stunnel -version"
(although in stunnel.conf, there is specified fips=no):

And here is log (debug=7):

It connects just fine, just to default service.

s_client connects to proper service (using this command)
C:\openssl s_client -connect 213.175.91.220:443
-cert cert.crt -key key.key -servername servername

Client authentications succeeds in either case (as expected)
