I'm running on GKE, and connected to my cluster using the proxy command. when I visit localhost:8001/ui, I get this error.

Error: 'ssh: rejected: connect failed (Connection refused)' Trying to reach: 'http://10.56.40.3:9090/'

Is there something wrong with some system service? How can I just bounce the ui deployment? I can't seem to find in the docs where this service is even defined.
