Can you contact Elasticsearch on that URL using curl?

Yes, if using this curl

curl -k -u elastic:"password;" https://192.168.0.92:9200

{
  "name" : "node-1",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "h8EzxHyvQyiMyU2I6gzaZQ",
  "version" : {
    "number" : "7.1.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "606a173",
    "build_date" : "2019-05-16T00:43:15.323135Z",
    "build_snapshot" : false,
    "lucene_version" : "8.0.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}
