I have below architecture in my project
My UI Service(Port 8080) making Feign call to Gateway Service(Port 8085).
My Get call from UI service is " http://localhost:8080/invoice-list?startDate=2018-08-05&endDate=2018-10-05 "
Similar call from Gateway Service "http://localhost:8085/invoice-download-service/invoice-list?startDate=2018-08-05&endDate=2018-10-05"
When i make this GET call from UI service i get below error within minute
is feign.RetryableException: Read timed out executing GET http://localhost:8085/invoice-download-service/invoice-list?startDate=2018-08-05&endDate=2018-10-05] with root cause
java.net.SocketTimeoutException: Read timed out
But when i make direct call from Gateway Server to microservice, i dont get error.
Application.properties file of Gateway service
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=160000000
ribbon.OkToRetryOnAllOperations=true
ribbon.ReadTimeout=5000000
ribbon.ConnectTimeout=5000000
ribbon.MaxAutoRetries=3
ribbon.MaxAutoRetriesNextServer=3
zuul.host.socket-timeout-millis= 5000000
zuul.host.connect-timeout-millis= 5000000
Here i have set readtimeout and connecttimeout property around 8 to 10 min, hence i am not getting error.
Application.properties file of UI service
spring.application.name=external-ui-service
server.port=8080
Here in UI service i dont have timeout property. I tried above properties here but not working. Obviously this UI service is not using ribbon,zuul etc. This is just an making Feign call to gateway.
So what should i do to increase timeout in UI service?

Feign Client is pretty configurable. In terms of a timeout, it allows us to configure both read and connection timeouts. Connection timeout is the time needed for the TCP handshake, while the read timeout needed to read data from the socket. Connection and read timeouts are by default 10 and 60 seconds, respectively.
public class RetryableException extends FeignException. This exception is raised when the Response is deemed to be retryable, typically via an ErrorDecoder when the status is 503.
Root Cause This problem is caused by an environment issue, such as: Server is trying to read data from the request, but its taking longer than the timeout value for the data to arrive from the client. Timeout here would typically be tomcat connector -> connectionTimeout attribute.
Added below properties in UI Service's application.propeties file.
feign.client.config.default.connectTimeout: 160000000
feign.client.config.default.readTimeout: 160000000
