Hello everyone,

I have a problem with my .siem-signals-default index. The shard goes to red status and I can't reallocate the shard to another node. Because the shard seems to not be in my cluster and I can't get it back. See the message below:

```auto
"index" : ".siem-signals-default-000003",
  "shard" : 0,
  "primary" : true,
  "current_state" : "unassigned",
  "unassigned_info" : {
    "reason" : "CLUSTER_RECOVERED",
    "at" : "2021-12-15T10:17:49.049Z",
    "last_allocation_status" : "no_valid_shard_copy"
  },
  "can_allocate" : "no_valid_shard_copy",
  "allocate_explanation" : "cannot allocate because a previous copy of the primary shard existed but can no longer be found on the nodes in the cluster",

```

Has anyone encountered this problem? Or can someone tell me how to solve it?

Thanks a lot !

Welcome to our community! 😃

What is the output from the `_cluster/stats?pretty&human` API?
