Hi Patrice!
I’m experiencing a new error when I try to index new articles. I’ve attached a link to a screenshot for you.

Your Elasticsearch index is over used.

To prevent the message in Kibana:

PUT /_all/_settings
{
  "index.blocks.read_only_allow_delete": null
}

Or with ssh command line on your server directly:
curl -XPUT "https://localhost:9200/_all/_settings" -H 'Content-Type: application/json' -d'{ "index.blocks.read_only_allow_delete": null}'

Thank you, Patrice! It worked.
Best,

Is there an explanation of what this does and why it is helpful? And what cases it applies to or resolves?

This flag is raised by Elasticsearch when disk space is getting close to 100%: https://www.elastic.co/guide/en/elasticsearch/reference/7.9/modules-cluster.html#cluster-routing-flood-stage
But I noticed the index can be in read-only mode even if the disk has plenty of free space. Resetting the index.blocks.read_only_allow_delete flag is then a workaround.
