I have an app deployed to IBM Cloud as a liberty java application.

From the Cloud Foundry CLI on my local machine I can connect and run a command using

 cf ssh APP -c "ls -l"

With version

 $ cf -v
 cf version 6.26.0+9c9a261fd.2017-04-06

Attempting to run the same cf ssh * command from a Jenkins job on a server. This is always failing to connect to SSH. The jenkins job's build script already performs other cf operations such as cf push and cf start etc, I am just adding a new step which uses cf ssh, example:

 bx cf ssh rca-qa5 -c "ls -l"

This runs and hits a connection error with the following output

 + bx cf ssh rca-qa5 -c ls -l
 Invoking 'cf ssh rca-qa5 -c ls -l'...
 
 FAILED
 Error opening SSH connection: dial tcp zzz.zzz.zzz.zzz:2222: getsockopt: connection refused
 Build step 'Execute shell' marked build as failure

Am I missing some configuration for the jenkins server's IBM Cloud cli? Or is there any other reason why this might not be able to connect?

Edit: Add Jenkins IBM Cloud CLI version info

 + bx cf -v
 Invoking 'cf -v'...
 cf version 6.32.0+0191c33d9.2017-09-26
 + bx -v
 bx version 0.6.2+040af8d-2017-11-17T08:22:55+00:00
