Thanks a lot!
I have now installed cygwin64 from 
http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2019/08/30/171738

ssh now works fine. The version is
OpenSSH_7.0p1, OpenSSL 1.0.2t 10 Sep 2019

I see a change in both SSH and SSL versions here

Not working ssh version under cygwin64 was:
OpenSSH_8.1p1, OpenSSL 1.1.1d 10 Sep 2019

I was also trying to use the latest cygwin32 version that seemed to be 
working, but I noticed that git was behaving very odd - it didn't finish 
pull command quite often. I noticed git has dependency on the same 
openSSL 1.1 package, so I suspect there is an issue in that openSSL 1.1 
package that is used in both ssh and git.
