I have a binderhub deployment running on k8s via helm.
I am able to run notebooks on the binder instance, but when I try to connect via juniper I get failures when trying to connect to the websocket.
The container gets launched correctly, but then I get an uninformative error in the browser:
Firefox can’t establish a connection to the server at ws://...
Do I need to configure anything on my binderhub / jupyterhub deployment to enable these connections?
