After some coordinators node left from Elastic cluster and return we start to see this erros on the logs:
`org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];`.
And
`[2020-06-03T16:26:48,311][ERROR][o.e.x.s.a.e.NativeUsersStore] [elh-bhs-ovh017p] security index is unavailable. short circuiting retrieval of user [readall]`.
We are tryint to stabilish a cluster again since than with all nodes and just with master nodes too. We set some `gateway` params on our confs to a small number to start the recovery sooner but the result is the same.
Seems like even after master election and some data nodes join the cluster the recovery doesn't happen. There is some election retry even when a master already exists, who keeps failing non stop.

Solved.
We delete all data from all nodes and restart them, it's working fine now.
