How to use the ssh task in bamboo

[Marc Eastman]

I have an ssh key that I want to use to ssh onto a dev server from bamboo's server. I am able to ssh onto the dev server from bamboo's server if I get into the bamboo terminal using remote desktop (with ssh key copied over), but it fails if I try to ssh from within the "ssh task". I tried copying over the fingerprint for verification too but it says 

simple    05-Sep-2019 11:42:52 Connecting to  on port: 22
error    05-Sep-2019 11:42:53    Failed to connect to host
error    05-Sep-2019 11:42:53    java.net.ConnectException: Connection refused: connect

 I have checked that port 22 is open when outgoing, and I am able to ping the dev server from within a bamboo task, so whats going on here? Why can't I connect ssh from within a bamboo task?
