When I run the client locally and connect using 'localhost:1099' or '127.0.0.1:1099' the connection succeeds, but when I provide the computer's ip '192.168.10.136:1099' I get the printStackTrace() output below: g28:/home/noelia/Desktop# java -jar AppClient.jar javax.naming.CommunicationException: Could not obtain connection to any of these urls: 192.168.10.136:1099 and discovery failed with
