Hey, I am trying to setup DeviceHive Server on our Servers for a simulation activity. I have followed the steps as stated in the documentation - https://docs.devicehive.com/v2.0/docs/server-installation. The following services are running: Hazelcast - port 5701 - ./hzstart.sh Zookeeper & Kafka DeviceHive WS Proxy Server - port 6000 I started the Backend Server using the command - java -jar ${devicehive-java-server-directory}/devicehive-backend/target/devicehive-backend-<version>-boot.jar And its running but when I try to run the Frontend Service it fails with the error : Backend Server is not reachable. Can someone please advise on this error?

my code (python client): from devicehive import DeviceHiveApi urlauth = 'http://192.168.0.40:8090/dh/rest' login = 'dhadmin' password = 'dhadmin#911' device_hive_api = DeviceHiveApi(url_auth, login=login, password=password) info = device_hive_api.get_info() #working user = device_hive_api.get_current_user() #error "HTTP 404 Not Found"

from devicehive import DeviceHiveApi url_auth = 'http://192.168.0.40:8090/dh/rest' login = 'dhadmin' password = 'dhadmin_#911' device_hive_api = DeviceHiveApi(url_auth, login=login, password=password) user = device_hive_api.get_current_user()

Which port is used to start the Node server and where we need to define this.
