Hello, I am trying to configure stunnel on windows (version 5.69)

I am using the capi engine with below conf.
I am sending the logs to logstash and not sure if it is working or not. 
My questions are:
1) I dont see anything in the log after initializing the service. When it sends the logs through stunnel, should i see an entry in the logs?
2) When using capi engine, should i limit the ssl version still ? in your website i see that the tls version supposed to be limited but is it an old info?
3) in your website again it mentions that i should specify the security level to zero for capi engine, is it also a valid info? if yes, do i need to set it in global section or service level?
