Hi guys,

I'm receiving this error on my ECK:  
`Could not update cluster license: failed to revert to basic: 503 Service Unavailable:`

I installed it using the basic confirmations on the Quick start page.

When I try to get the license from kibana it works and the license is valid. Any guess?

This is just a warning. What it means is that the operator tried to make an API call to Elasticsearch (here in order to set the license) and Elasticsearch responded with a HTTP 503.

While error message is just a warning it still means your Elasticsearch cluster was unavailable at this point in time. Can you check e.g. with `kubectl get elasticsearch` if your cluster is available now? You said you were accessing the license UI in Kibana and that worked, which indicates that Elasticsearch is available (again), if so this could have been a transient issue.

Hey @pebrc

Actually my Elasticsearch is red cause that.

```
kubectl get elasticsearch -n logging
NAME HEALTH NODES VERSION PHASE AGE
elasticsearch-logs red 3 7.6.0 Ready 3d

kubectl get pods -n logging
NAME READY STATUS RESTARTS AGE
elasticsearch-logs-es-elasticsearch-logs-0 1/1 Running 0 3d20h
elasticsearch-logs-es-elasticsearch-logs-1 1/1 Running 0 3d20h
elasticsearch-logs-es-elasticsearch-logs-2 1/1 Running 0 3d20h
kibana-logs-kb-7fb98c6685-8fvlq 1/1 Running 0 3d2h

```

And here the describe:

```

So that explains it. The license message is just a symptom of your cluster being unavailable. The next step is to find out why your cluster is `red`.

We have a few troubleshooting tips here: [https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-troubleshooting.html](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-troubleshooting.html)

It would be interesting for example to look at the Elasticsearch logs to find out what happened.

And here my kibana logs:

and if I check the license from Kibana UI it works:

```
{
  "license" : {
    "status" : "active",
    "uid" : "xxx",
    "type" : "basic",
    "issue_date" : "2020-02-20T16:46:08.569Z",
    "issue_date_in_millis" : 1582217168569,
    "max_nodes" : 1000,
    "issued_to" : "elasticsearch-logs",
    "issuer" : "elasticsearch",
    "start_date_in_millis" : -1
  }
}
```

`FORBIDDEN/12/index read-only` are your Elasticsearch nodes running out of disk space by any chance?

I am thinking of [https://www.elastic.co/guide/en/elasticsearch/reference/current/disk-allocator.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/disk-allocator.html) where Elasticsearch sets your indices to read-only when you exceed 95% disk usage (by default, can be configured)
