Search API is not working from other server

Hi All,

When I am trying to call elasticsearch URL from SOAP UI. POST and DELETE call is working, however GET is throwing connection reset error.
Can anyone please suggest , how to resolve it.

PS: search is not working with both POST and GET

POST http://ip:9200/testtoken/_doc/TestService
"ServiceName" : "TestService",
"accessToken" : "accessToken",
"refreshToken" : "refreshToken",
"idToken" : "idToken",

GET http://ip:9200/testtoken/_search?q=ServiceName:TestService

DELETE http://ip:9200/testtoken/_doc/TestService
