Comment 4 for bug 2040271

It worked after adding both vault:certificates and ceph-dashboard:iscsi-dashboard relations.

Not so sure why the health check from the dashboard didn't work with HTTP, but in any case, this kind of setup steps should be documented appropriately even if it's a limitation from an upstream.

[before adding a vault relation for certificates but after adding the dashboard relation]

# ceph dashboard iscsi-gateway-list | jq .
{
  "gateways": {
    "new-troll.maas": {
      "service_url": "http://admin:XKFUJ7HR@192.168.151.103:5000"
    },
    "robust-lion.maas": {
      "service_url": "http://admin:XKFUJ7HR@192.168.151.104:5000"
    }
  }
}

^^^ using HTTP as expected.
