Right. No firewalls. This is my 'toy' environment running as virtual machines on my desktop computer. I'm playing with this here because have the same problem on my real cluster. Will try to explicitly configure starting IP for this SNN.

In your logs, its starting SNN webserver at 0.0.0.0:50090. Its better if we provide which IP it should start at. Also I am assuming you are not having any firewalls enable between these 2 machines right ?
