dial tcp 10.X.X.X:3000: connect: connection refused (CrashLoopBackOff on rocketchat-rocketchat pod)

Deploying this Helm chart, the first thing I see is this:

[root@kube2-lon rocketchat]# k get pods -o wide

Logs for that pod show this:

Ideas?

values.yaml:

host: rocket.core.xxx.net
mongodb:
  auth:
    passwords:
      - rocketchat
    rootPassword: xxx
ingress:
  enabled: true
  tls:
    - secretName: cert-rocket.core.xxx.net
      hosts:
        - rocket.core.xxx.net
        - rocket

(I've also tried a simpler values.yaml with just the mongodb parts, uninstalled, deleted PVCs, and installed - same result).

Interesting, in the mongodb container:

[root@kube2-lon rocketchat]# k exec -it  rocketchat-mongodb-0 -- bash
Defaulted container "mongodb" out of: mongodb, volume-permissions (init)
I have no name!@rocketchat-mongodb-0:/$

At this point it pretty clearly seems like a bug.

MongoServerSelectionError: Server selection timed out after 30000 ms

From: /app/bundle/programs/server/npm/node_modules/meteor/promise/node_modules/meteor-promise/promise_server.js:218

Can give a full stack trace if interest from the devs.

A lot turning up on Google (cursory search: https://www.google.com/search?client=firefox-b-d&q=rocket+chat+MongoServerSelectionError).
