Kibana a new nodes does not get listed but the total number of nodes is correct

Elastic Stack Elasticsearch
1

Hi,
I added a new node to an elastic cluster with a master node (hot) and a warm node.
The cluster status is green and shows 3 nodes.

Elastic is on all machine 7.15.2
the nodes are monitor (master hot), monitor-1 (warm), monitor-2 (hot).

Kibana stack monitor overview display 3 nodes, the nodes page in the status bar shows 3 nodes but in the node list, only 2 are present.

the output of the command
GET /_nodes?filter_path=nodes.*.name

{
  "nodes" : {
    "_U-mUDKKTBu4lyxfVXQ4qA" : {
      "name" : "monitor-2"
    },
    "AARBMvg_T02d183k3HPirA" : {
      "name" : "monitor-1"
    },
    "KL2ZW-FtTkOB7uJ82cgT6w" : {
      "name" : "monitor"
    }
  }
}

the output of the command

GET .monitoring-es-*/_search?filter_path=aggregations.node_ids
{
  "size": 0,
  "query": {
    "term": {
      "type": {
        "value": "node_stats"
      }
    }
  }, 
  "aggs": {
    "node_ids": {
      "terms": {
        "field": "node_stats.node_id",
        "size": 50
      }
    }
  }
}

returns

{
  "aggregations" : {
    "node_ids" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : "KL2ZW-FtTkOB7uJ82cgT6w",
          "doc_count" : 53657
        },
        {
          "key" : "AARBMvg_T02d183k3HPirA",
          "doc_count" : 53656
        }
      ]
    }
  }
}

Any suggestion?

Thanks
