I am trying to re-index from 6.7 to 7.3.

root@elk730 ~ $curl -X POST "localhost:9200/\_reindex?pretty" -H 'Content-Type: application/json' -d'  
{  
"source": {  
"remote": {  
"host": "[http://10.10.10.60:9200](http://10.10.10.60:9200)"  
},  
"index": "reindexed-v630-test"  
},  
"dest": {  
"index": "v730-test"  
}  
}'  
{  
"error" : {  
"root\_cause" : [  
{  
"type" : "connect\_exception",  
"reason" : "Connection refused"  
}  
],  
"type" : "connect\_exception",  
"reason" : "Connection refused"  
},  
"status" : 500  
}

elasticsearch.yml has this setting already.

reindex.remote.whitelist: "10.10.10.60:9200"
