I'm trying to build testbed environment of gen3 using docker-compose ('compose-services'). However following error found on guppy service which infers unavailability of esproxy-service.

However esproxy servrice is available if accessed standalone at http://esproxy-service:9200. I guess some configuration error. Pls suggest.
