I have a simulator for one of the microservice that I am consuming . Both my microservice and the simulator are deployed on local host and I am able to invoke the simulator from curl but when it is invoked from Java Feign client I am getting connection Refused from the Feign client . 1)I have already checked that the simulator is up and running on the port
netstat -a

2) I am able to invoke the simulator from Curl
curl -v -X GET -H "X-B3-ParentSpanId:9b9c585fae4b6909" -H "X-B3-Sampled:1" -H "X-B3-TraceId:897aa305e5cd4a0e9b9c585fae4b6909" http://127.0.0.1:19092/restservices/oda/v1/flow/partner/BBY/reference/29920299209700018540
Note: Unnecessary use of -X or --request, GET is already inferred.

But when it is invoked from my microservice via Feign client it is giving me connection Refused error
"label" : "feign.RetryableException: Connect to [localhost/127.0.0.1] failed: Connection refused executing GET http://127.0.0.1:19092/restservices/oda/v1/flow/partner/BBY/reference/29920299209700018540"
I solved this problem
turns out there are two same remote services
and one of them didn‘t start success
so i turn down the duplicate service
hope this solve you problem
