Getting 502 bad gateway for a particular query

Elastic Stack Kibana
1 
GET */_search
{
  "size": 10000,
  "query": {
    "bool": {
      "should": [
        {"match": {"imei": "value"}},
        {"match": {"imei1": "value"}},
        {"match": {"IMEI": "value"}}
      ]
    }
  }
}

this same query is working on all other servers except one. Also on the same server where I am getting 502, other queries are working fine.

Below is the error I am getting here.

<html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
<hr><center>openresty</center>
</body>

Looks like you will want to check the logs/status of openresty, which is not affiliated with Kibana.
