From mkopinsky via Slack:

/Applications/Ballista.app/Contents/MacOS/Ballista --help

error sending request for url (https://redacted:8443/webstart/client-lib/hapi-1.1.jar): connection closed before message completed

Later the below fix was applied by him, locally, to resolve the issue.

I added
.pool_max_idle_per_host(0)
to client builder and I was able to get in via ballista!!!!
